First order reactions

Question

The correct difference between first and second order reactions is that

Easy

Solution

$\text{For the first order reaction,}{t}_{1/2}=\frac{0.693}{k}$

$\text{which is independent of initial concentration}[A{]}_{0}$

$\text{For second order reaction,}{t}_{1/2}=\frac{1}{k[A{]}_{0}}$

Half life depends on initial concentration of reactant.
