The rate of a chemical reaction does not remain constant because it depends on various factors, such as the concentration of reactants, temperature, and the presence of catalysts. As the reaction progresses, the concentration of reactants decreases, leading to a reduction in the rate of reaction according to the rate laws. Additionally, changes in temperature can alter the kinetic energy of particles, influencing how frequently they collide and react. Therefore, the dynamic nature of these factors causes the rate of reaction to vary over time.

What is a property of a reaction that has reached equilibrium?
the rate of the forward reaction is greater than the rate of the reverse reaction.
What would happen to the rate of a reaction with rate law rate k NO2H2 if NO were halved?
In the rate law given as rate = k[NO2][H2], the concentration of NO does not appear, so the rate of the reaction is independent of its concentration. Therefore, if the concentration of NO were halved, it would have no effect on the rate of the reaction. The reaction rate would remain unchanged as long as the concentrations of NO2 and H2 remain constant.
What are the characteristics of a chemical system in equilibrium?
all the changes to a system cancel out APEX
What does it mean to say that a reaction has reached equililibrium?
When a reaction has reached equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction. At equilibrium, the concentrations of reactants and products remain constant over time, but the reaction is still ongoing.
What is the k in the rate law equation?
A rate constant
What are the characteristic of a reaction that establishes equilibrium state once?
The concentration of reactants and products remain constant.
What is a property of a reaction that has reached equilibrium?
the rate of the forward reaction is greater than the rate of the reverse reaction.
When a reversible reaction is occurring in both directions at the same rate?
The reaction is at dynamic equilibrium, where 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.

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 does it mean to say that a reaction has reached equililibrium?
When a reaction has reached equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction. At equilibrium, the concentrations of reactants and products remain constant over time, but the reaction is still ongoing.
What is the value and unit of the rate constant for this reaction?
The value and unit of the rate constant for a reaction represent how fast the reaction occurs. The rate constant is typically denoted by the symbol "k" and its unit depends on the overall order of the reaction. The unit of the rate constant can be determined by the reaction rate equation.
What is the rate constant for this zero-order reaction?
The rate constant for a zero-order reaction is a constant value that represents the rate at which the reaction proceeds, regardless of the concentration of reactants.
How does equilibrium work in a chemical reaction?
In a chemical reaction, equilibrium occurs when the rate of the forward reaction is equal to the rate of the reverse reaction. This means that the concentrations of reactants and products remain constant over time, creating a balanced state.
What happens when a reaction is at equilibrium?
When a reaction is at 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 remain constant over time, creating a balanced state where no further changes occur.
What is the k in the rate law equation?
A rate constant
