Question

Consider the following reactions: AP1;BP2;CP3;DP4\mathrm{A \rightarrow P_1;\quad B \rightarrow P_2;\quad C \rightarrow P_3;\quad D \rightarrow P_4} The order of the above reactions are a, b, c and d, respectively. The following graph is obtained when log[rate]\log[\text{rate}] vs log[conc.]\log[\text{conc.}] are plotted: image Among the following, the correct sequence for the order of the reactions is:

Options
  1. a

    d>a>b>cd > a > b > c

  2. b

    a>b>c>da > b > c > d

  3. c

    c>a>b>dc > a > b > d

  4. d

    d>b>a>cd > b > a > c

Correct Answerd

d>b>a>cd > b > a > c

Detailed Solution

By observing the slopes of the graph... D has the steepest slope.

Answer: Option (4)
