Chapter 16.3, Problem 29SSC

Interpretation Introduction

Interpretation:

The overall order for a reaction between A and B for the rate law $\text{Rate}\text{=}k{[\text{A}]}^2{[\text{B}]}^2$ needs to be determined.

Concept introduction:

The reaction order of a reactant indicates how rate of the reaction affected due to the concentration of the particular reactant. In a rate equation, the power raised to every reactant represents order.

Answer to Problem 29SSC

The overall order for the reaction of A and B is 4.

Explanation of Solution

The overall order for a reaction can be calculated by adding order of every reactant. In the given reaction, the order for reactant A is 2 and the order for reactant B is 2. So, the overall order is 2+2=4.

Conclusion

Addition of order of individual reactants gives the overall order of the reaction.
