Does increasing the surface area increase or decrease the rate of a chemical reaction?
It will increase the rate of the reaction because more particles will be exposed and they will be able to react.This decreases the time to react.
How is the rate of reaction affected when the temperature increases?
As the temperature increases, the reaction time decreases.
What happens to the reaction rate when reactants particles collide more often?
In brief, the reaction rate increases. When there are more collisions, the more probability to collide them in the proper direction. The overall reaction will come to the equilibrium in a lesser time.
What does it mean for a reaction to be a equilibrium?
In a particular time, if the forward and backward reactions of a reversible reactions take place in the same rate, there would be not a visible change (i.e. no net change) in the system, and that system is said to be at equilibrium.
What is a property of a reaction that has reached equilibrium?
At equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction. This means the concentrations of reactants and products remain constant over time.
How does the amount of time given affect the rate of the enzymatic reaction?
it will increase the time of the chemical reaction
What effect does the concentration of reactants have on the the rate of a reaction?
The effect of concentration of reactants on rate of reaction depends on the ORDER of the reaction. For many reactions, as the concentration of reactants increases, the rate of reaction increases. There are exceptions however, for example a zero order reaction where the rate of reaction does not change with a change in the concentration of a reactant.

How is the rate of reaction affected when the temperature increases?
As the temperature increases, the reaction time decreases.
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.
During dynamic equilibrium how do forward reaction rate and reverse reaction rate compare?
In dynamic equilibrium, the forward reaction rate (rate of reactant conversion to products) is equal to the reverse reaction rate (rate of reformed products converting back to reactants). This results in a constant concentration of reactants and products over time, signifying a balanced state where no net change in concentration occurs.
What is a following characterizes a reaction at 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 over time. The equilibrium constant, which is the ratio of product concentrations to reactant concentrations, is constant at a given temperature.
What is the effect varying the concentration on the rate of reaction time?
Increasing the concentration of reactants generally increases the rate of a reaction because there are more reactant particles available to collide and form products. This leads to more frequent and successful collisions, ultimately speeding up the reaction time.
What happens to the reaction rate when reactants particles collide more often?
In brief, the reaction rate increases. When there are more collisions, the more probability to collide them in the proper direction. The overall reaction will come to the equilibrium in a lesser time.
What factors change the rate of chemical reaction?
Factors that can change the rate of a chemical reaction include temperature, concentration of reactants, presence of a catalyst, surface area of reactants, and pressure (for gas-phase reactions). Increasing temperature generally speeds up reactions by providing more energy for molecules to react.
Why the rate of reaction of lithium with water increases over time?
The rate of reaction of lithium with water increases over time because as the reaction proceeds, more lithium surfaces become exposed to water, leading to more collisions and interaction between the lithium and water molecules. This increased surface area allows for a higher rate of reaction to occur as the reaction progresses.
How is the rate of reaction compared with the time the reaction is carried out?
The rate of reaction is a measure of how quickly reactants are converted into products per unit time. It is often expressed as the change in concentration of reactants or products over time. The time a reaction is carried out can influence the rate by affecting factors such as temperature, concentration, and presence of catalysts.
