In a chemical system, there are forward and reverse reactions occurring constantly. As the forward reactions progress, the increased amount of products allows for more and more reverse reactions. Once the rate of the forward and reverse reactions are equal, the system is at equilibrium. The forward and reverse reactions continue at equal but opposite rates; however, there are no further changes in the concentration of the products and reactants.
At chemical equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction. This means that the concentrations of reactants and products no longer change over time. The system appears to be in a state of balance, but the reactions are still occurring in both directions.
If a chemical reaction has reached equilibrium, then it means that the rate of forward reaction is equal to rate of backward reaction.
It means that substances on left hand side and right hand side of chemical reaction are being formed at the same rate.
The ratio of the products to reactants remains constant over time.
The molecules continue to randomly move as usual, but we observe no "net movement."
When a chemical reaction reaches equilibrium it means that neither the forward nor the reverse reaction have stopped.

What are used to show what happens during a chemical reaction?
Chemical equations are used to show what happens during a chemical reaction. They demonstrate the reactants that are used, the products that are formed, and the balanced relationship between them. Symbols and formulas represent the different elements and compounds involved in the reaction.
When a chemical reaction proceeds in both directions the reaction is?
When a chemical reaction proceeds in both directions, it is referred to as a reversible reaction. In a reversible reaction, reactants are converted into products, and products can also react to form reactants. This results in a dynamic equilibrium where the rates of the forward and reverse reactions are equal.
How do chemical manufacturers make the reaction continue to make ammonia once the reaction has reached equilibrium?
Manufacturers can shift the equilibrium of the reaction towards ammonia by continuously removing ammonia as it is formed or by adding more reactants to drive the reaction forward. This process helps maintain a higher concentration of ammonia and promote the reaction's progress.
What correctly describes any chemical reaction that has reached equilibrium?
At equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction. The concentrations of reactants and products remain constant, although they are still reacting. The equilibrium position can be affected by changes in temperature, pressure, or concentration.
What temperature is the reaction at equilibrium?
The temperature at which a reaction reaches equilibrium can vary depending on the specific reaction and its conditions. For some reactions, the temperature at equilibrium may be higher, while for others it may be lower. The equilibrium temperature is determined by the enthalpy change of the reaction and the equilibrium constant.
What is difference between physical and chemical balance?
The difference is that chemical equilibrium is the equilibrium of products and reactants in a reaction while physical equilibrium is the equilibrium of the physical states of the same substance.
In chemical equilibrium what happens when Q is greater than K?
When Q is greater than K in a chemical reaction, it means the reaction is not at equilibrium. This indicates that there are higher concentrations of products compared to reactants, so the reaction will shift in the reverse direction to decrease Q and reach equilibrium.
Chemical equilibrium is a form of equilibrium?
because in chemical equilibrium the rate of forward reaction is = the rate of reversed reaction so in both sides at left side and right side those products which are formed are in same quantities that's why chemical equilibrium is the form equilibrium
When does chemical equilibrium occur?
Chemical equilibrium occurs when the rate of the forward reaction equals the rate of the reverse reaction in a closed system, leading to a constant concentration of reactants and products. This state represents a balance between the opposing reaction rates, with no net change in the concentration of substances involved in the reaction.
What happens after equilibrium?
Rate of forward reaction=rate of backward reaction
What happens when a chemical change does not go to completion?
When a chemical change does not go to completion, some reactants may remain after the reaction has reached equilibrium. This can result in a mixture of both reactants and products in varying amounts. The extent to which a reaction goes to completion depends on factors such as reaction conditions, reactant concentrations, and the presence of catalysts.
When a chemical reaction and it and reverse are occurring at the same time and at the same rate the reaction has achieved?
equilibrium
What term refers to the condition in which the concentration of the reactants and products remains constant over time?
Chemical equilibrium describes a state in which the concentrations of reactants and products in a reversible chemical reaction remain constant over time. At equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction.
What is an equalibrium constant?
The equilibrium constant (K) is a measure of the extent of a chemical reaction reaching equilibrium. It is the ratio of the concentrations of products to reactants at equilibrium, each raised to the power of their respective stoichiometric coefficients. It is a crucial parameter in determining the position of equilibrium in a chemical reaction.
Which of the following factors does not affect thr equilibrium of a chemical reaction when it is changed?
The nature of the reactants and products does not affect the equilibrium of a chemical reaction when it is changed. The equilibrium constant is a characteristic of a particular reaction at a given temperature and does not depend on the identities of the substances involved.
When does a chemical reaction reaches equilibrium?
A chemical reaction reaches equilibrium when the forward and reverse reactions occur at the same rate, meaning the concentrations of reactants and products remain constant over time. At equilibrium, the ratio of concentrations of products to reactants, known as the equilibrium constant, remains constant.
Describes chemical equilibrium?
Chemical equilibrium is a state in a chemical reaction where the forward and reverse reaction rates are equal, resulting in no further change in the concentrations of reactants and products. At equilibrium, the concentrations of reactants and products remain constant, but the reaction is still occurring. The equilibrium constant, K, expresses the relationship between the concentrations of reactants and products at equilibrium.
