Question
A reaction is catalysed by H+ ion;and in the rate law the dependence of rate is of first order with respect to the concentration of H+ ions, in presence of HA rate constant is 2 × 10-3 min-1 and in presence of HB rate constant is 1 × 10-3 min-1. HA and HB have relative strength as :
Options
A.0.5
B.0.002
C.0.001
D.2
Solution
We know
Rate = k [conc.]
Given Rxn catalysed by HA and HB
Rate constant kA = k1 [H+]A
kB = k1 [H+]B
Then relative strength of acids A and B is
= strength of 
Rate = k [conc.]
Given Rxn catalysed by HA and HB
Rate constant kA = k1 [H+]A
kB = k1 [H+]B
Then relative strength of acids A and B is
