Question

Consider the following reactions A P1 ; B P2 ; C P3 ; D P4, The order of the above reactions are a, b, c and d, respectively. The following graph is obtained when log[rate] vs.log[conc.] are plotted : Among the following, the correct sequence for the order of the reactions is :

(A) d > b > a > c
(B) a > b > c > d
(C) c > a > b > d
(D) d > a > b > c

Correct answer: A. Rate = K[Conc]order logRate = log K + order log[conc] so slope of graph is order of reaction. greater the slope greater is order of reaction so order of reaction  “A < B < C < D”
