Consider the following reactions A → P 1 ; B → P 2 ; C → P 3 ; D → P 4 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 :

Options

  1. Ad > a > b > c
  2. Ba > b > c > d
  3. Cc > a > b > d
  4. Dd > b > a > c

Correct answer

D. d > b > a > c

Step-by-step solution

Rate = K [ Conc ] order  logRate = logK + order ×   log [ conc ] so slope of graph is order of reaction. greater the slope greater is order of reaction so order of reaction ⇒ " c < a < b < d ' '
