(a) The rate of reaction increases in presence of catalyst. Explain the statement by plotting a curve between reaction coordinate and energy.
(b) For a reaction, the initial concentration of reactant is 0.4 M and rate constant is `2.5xx10^(-4)"mol L"^(-1)s^(-1).` Calculate the half-life period of the reaction.

Text Solution

Verified by Experts

`[(b)" Units of k show that reaction is of zero order "t_(1//2)=([A]_(0))/(2k)=(0.4)/(2xx2.5xx10^(-4))s=1800s]`
