Assertion (A): Decomposition of hydrogen peroxide catalysed by I is a bimolecular first order reaction.

Question

Assertion (A): Decomposition of hydrogen peroxide catalysed by I^-1 is a bimolecular first order reaction. 

Reason (R): The above reaction take place in two steps,

step 1 involves both H₂O₂ and I and so it is bimolecular but order is determined experimentally as 1. 

(a) Both A and R are correct and R is the correct explanation of A. 

(b) Both A and R are correct but R is not the correct explanation of A 

(c) A is correct but R is wrong 

(d) A is wrong but R is correct

Answer 1

(a) Both A and R arc correct and R is the correct explanation of A
