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 :
(1) d > b > a > c
(2) a > b > c > d
(3) c > a > b > d
(4) d > a > b > c

(1) d > b > a > c
Explanation:
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”
