Rate Law for the Overall Reaction
The rate law for a chemical reaction describes how the rate of the reaction depends on the concentrations of the reactants. It is determined experimentally by measuring the reaction rate at different concentrations of the reactants and analyzing the data.
In this case, the chemical reaction is described as proceeding through multiple steps. The rate law for the overall reaction can be determined by considering the slowest step, which is often referred to as the rate-determining step. The rate-determining step is the step with the highest activation energy, and it limits the overall rate of the reaction.
To determine the rate law for the overall reaction, we need to consider the rate-determining step and the stoichiometry of the reaction. The rate law is expressed in terms of the reactant concentrations involved in the rate-determining step.
In this question, the rate law for the overall reaction is given as:
Rate = K[A]²[B]
Explanation:
- The rate law includes the rate constant (K), which is specific to the reaction and determined experimentally.
- The reactant concentrations are represented by [A] and [B], with [A]² indicating that the concentration of A is squared in the rate law.
- The concentration of B is also included in the rate law, indicating that it affects the rate of the reaction.
- The rate law suggests that the reaction rate is proportional to the square of the concentration of A and the concentration of B.
This rate law suggests that the reaction is second order with respect to A (since the concentration of A is squared) and first order with respect to B. Overall, the reaction is third order in total.
It is important to note that the rate law can only be determined experimentally and cannot be predicted solely based on the balanced chemical equation. The rate law provides insights into the reaction mechanism and the factors that influence the reaction rate.
