In the reaction, P + Q `rarr` R + S, the time taken for 75% reaction of P is twice the time taken for 50% reaction of P. The concentration of Q varies with reaction time as shown in figure. The overall order of the reaction is

A

2

B

3

C

0

D

1

Text Solution

Verified by Experts

The correct Answer is:
D
This is a first order reaction because `t_(75%)=2xxt_(50%)` The graph shows that the order with respect to Q is 0 so we can write the rate expression as rate =`k[P]^(1)[Q]^(0)`
