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

Text Solution

Verified by Experts

The correct Answer is:
D
Since time taken for 75% reaction of P is twice the time taken for 50% reaction of P. Hence reaction is first order w.r.t. P. Analysis of graph of Q w.r.t. time shows, reaction of Q is of zero order. Hence overall order of the reaction is one.
