In: Chemistry
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
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
