Question

2. TheratelawforthereactionA+BProductswasfoundtoberate=k[A][B]2.

a. What is the reaction order with respect to A?

b. What is the reaction order with respect to B?

c. What is the overall order of the reaction?

d. If the concentration of A is doubled while B is left unchanged, what happens to the rate of the reaction?

e. If the concentration of B is doubled while A remains unchanged, what happens to the rate of the reaction?

f. What does k represent in the rate law expression? What are the units of k for this reaction?

Explanation / Answer

A:- The order of the reaction is defined as (n ) sum of the powers of concentration terms in rate reaction

    (a) The order of the reaction with respect to A is first order.

     (b) The order of the reaction with respect to B is secon order.

      (c) The order of the overall reaction is third order.

       (d) The rate of the reaction is increases 4 times => 2n ,n=2

       (e) The rate of the reaction is remains same.

       (f) k is rate constant, Units for =mol-2.L2.s-2
