(a) The activation energy of a reaction is 100 kJ/mol. In the presence of
catalyst the activation energy is decreased by 75%. What is the effect on
rate constant of the reaction at 20º C ?
(b) A + 2B =>3C + 2D
The rate of disappearance of B is 1 x 102 mol L1 sec1. What will be
(i) rate of reaction (ii) rate of change in the concentration of A and C ?
