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` |

Answer» Correct Answer - D Overall order reaction can be decided by the data given `t_(75%) = 2t_(50%)` `:.` It is a first order reaction with respect to `P`. form graph `[Q]` is linearly decreaisng with time, i.e., order of reaction w.r.t. `Q` is zero and the rate expresison is `r = [P]^(1)[Q]^(0)`. Hence (d) is correct.Correct Answer - D Overall order reaction can be decided by the data given `t_(75%) = 2t_(50%)` `:.` It is a first order reaction with respect to `P`. form graph `[Q]` is linearly decreaisng with time, i.e., order of reaction w.r.t. `Q` is zero and the rate expresison is `r = [P]^(1)[Q]^(0)`.
