How can you tell from a graph when a reaction is finished?
In a graph of reaction progress versus time or concentration, a finished reaction typically shows a plateau where the values remain constant. This indicates that the reactants have been fully consumed and the products have reached equilibrium. The reaction rate becomes zero at this point.
What occurs when the forward and reverse reactions occur at the same rate?
If a forward and reverse reaction happen at the same rate, the result is called a dynamic equilibrium; the overall chemical composition does not change, even though reactions are constantly taking place.
What happens to the reaction rate as the reaction gets used up?
The reaction rate depends on the order of the reaction. In general (except for zero order), as the reaction progresses, the rate decreases with time.
How would the equilibrium concentration of H2O be affected by adding a catalyst to the mixture?
Adding a catalyst to the mixture would not affect the equilibrium concentration of H2O. A catalyst speeds up the rate of the forward and reverse reactions equally, without changing the position of the equilibrium. This means that the equilibrium concentration of H2O would not be affected by the presence of a catalyst.
What happens if you add energy to either side of a dynamic equilibrium?
If you add energy to one side of a dynamic equilibrium, the equilibrium will shift in the direction that consumes or uses up that energy to try and counteract the change. This shift will help to restore the equilibrium by balancing out the energy input.
Can the equilibrium constant equal zero?
No, the equilibrium constant (K) cannot equal zero. A zero equilibrium constant would mean that the reaction does not proceed in either direction, which contradicts the fundamental nature of chemical reactions to reach an equilibrium state.
If the equilibrium constant of a reaction is one what is the free charge?
Zero, if you mean what is the free energy change.
When does an equilibrium occur?
An equilibrium occurs when the rate of the forward reaction equals the rate of the reverse reaction. This means that the concentrations of reactants and products remain constant over time. Equilibrium can only be reached in a closed system under certain conditions, such as constant temperature and pressure.
Can chemical equilibruim be zero?
No, the equilibrium constant might only become zero in the (irrational) situation when NO product(s) is (are) formed, thus when there is NO reaction AT ALL. This will only happen at zero Kelvin.
How is constant velocity and equilibrium related?
Constant velocity occurs when an object is moving at a consistent speed in a straight line with no change in direction. Equilibrium, on the other hand, is a state where the net force acting on an object is zero, resulting in no acceleration. When an object is moving at a constant velocity, it is also in equilibrium because the forces acting on it are balanced, leading to no change in its motion.
What is meant by law of equilibrium?
The law of equilibrium refers to the condition where two opposing forces or factors are balanced and cancel each other out. In the context of physics, it describes the state when an object is either stationary or moving at a constant velocity with zero net force acting on it. This law is fundamental in understanding the stability and behavior of systems in various fields of science and engineering.

How do you recognize an object in equilibrium?
An object is in equilibrium when the net force acting on it is zero and the sum of all torques acting on it is also zero. To recognize this, you can check if the object is at rest or moving at constant velocity with no acceleration in any direction.
What are the conditions for equilibrium?
The two conditions of equilibrium are: 1. Concurrent Equilibrium the sum of vector forces through a point is zero. 2. Coplanar equilibrium, the sum of forces in a plane is zero and the sum of the torques around the axis of the plane is zero. These two conditions are similar to Ohms Laws in Electricity: Ohms Node Law the sum of the currents at a node is zero and Ohms Voltage law, the sum of the voltages around a loop is zero. These equilibrium conditions reflect the Quaternion mathematics that controls physics. Quaternions consist of a scalar or real number and three vector numbers. Equilibrium is the Homogeneous condition of a quaternion equation: the sum of the scalars or real numbers must be zero AND the sum of the vector numbers must also be zero. Thus there are TWO Conditions for Equilibrium. However if we were to use quaternions as nature does, then Equilibrium would be simplified to the zero quaternion condition.
Why every action has reaction?
Every action has an equal and opposite reaction to achieve Equilibrium where the forces sum to zero.
What is the k in the rate law equation?
A rate constant
What happens when balanced forces acting on an object?
The object remains in constant, uniform motion. That means its speed and direction of motion don't change. Note that its speed may or may not be zero.
