Question

Write the relationships between rate constant and half life of fist order and zeroth order reactions.

Answer 1

(a) For first order reaction, half-life period t_1/2 is, t_1/2 \(=\frac{0.693}{k}\) where k is the rate constant.

(b) For zeroth-order reaction, half half period (t_1/2) is, t_1/2 = \(\frac{[A]_0}{2k}\) where k is the rate constant and [A]₀ is initial concentration of the reactant.
