The half life period for catalytic decom...

The half life period for catalytic decomposition of `AB_(3)` at 50 mm is found to be 4 hrs and at 100 mm it in 2 hrs. The order of reaction is :

A

3

B

1

C

2

D

0

Text Solution

Verified by Experts

The correct Answer is:
B
`t_(1/2) propto a^(1-n)`
`(4 propto (50)^(1-n))/(2 propto (100)^(1-n)) rArr = 2 propto 2^(n-1)`
`therefore` n = 2
