Answer the following:
(a)
Define molecularity of a reaction. Give one difference between the order of reaction and its molecularity.
(b)
The rate constant ($k$) of a first order reaction is $4\cdot 5 \times 10^{-2}\text{ sec}^{-1}$. What will be the time required for the initial concentration of $0\cdot 4\text{ M}$ of the reactant to be reduced to $0\cdot 2\text{ M}$?
