If the observed rate law for a reaction is: rate = k(NO)(O3), the reaction is

A. first-order overall

B. first-order in O3

C. third-order overall

D. second-order in NO

Solutions

Expert Solution

rate = k(NO)(O3)

Power of NO=1

So, Order with respect to NO=1

Power of O3=1

So, Order with respect to O3=1

Overall order = sum of order of all the reactants = Order with respect toNO + Order with respect to O3

                                                                                           = 1 +1

                                                                              =2

So, overall order=2

From above explanation, Answer should be :

B. first-order in O3
