Q. Consider a chemical reaction involving compounds A and B, which is found to be first order in A and second order in B. At what rate will the reaction occur in experiment 2 ?
Experiment Rate $(Ms^{-1})$ Initial [A] Initial [B]
1 0.10 1.0 M 0.20 M
2 ? 2.0 M 0.60 M

Chemical Kinetics

Solution:

From first experiment
$0.1= K [1][0.2]^{2}$
$ K =2.5 $
$ r =2.5[2][0.6]^{2} $ In exp. II
$=1.8\, M s ^{-1}$
