The process of the reaction `A hArr nB` with time is represented in the fig, given below

The value of `n` is

A

1

B

2

C

3

D

1.5

Text Solution

Verified by Experts

The correct Answer is:
B
For time `t=` hour to time 5 hour
`Delta t = 4` hour
Decreases in conc. Of `A = 0.5-0.3=0.2 "mol L^(-1)`
Increase in conc. Of `B = 0.6 - 0.2 = 0.4 "mol L"^(-1)`
Thus in the same time interval, increase in concentration of B is double than decrease in conc. of A Hence `n=2`.
