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 the 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
Concentratino of Q is decreasing linearly, hence the order with respect to Q will be zero.
It is only first order reaction, tht
`(t_(75%)=2t_(50%))` hence the order with respect to 'P' will be one. Oveall order =1+=1
