Half life (t₁) of the first-order reaction and half life (t₂) of the second-order reaction are equal. Hence, assuming [A]₀ to be same, the ratio of the rate at the start of the reaction (assuming same initial concentration of the reactant in both the reactions) would be

Consider a gaseous reaction, the rate of which is given by K[A] [B], the volume of the reaction vessel containing these gases is suddenly reduced to 1/4^th of the initial volume. The rate of reaction relative to the original rate would be

During the particular reaction 10% of the reactant decompose in one hour 20% in two hours 30% in three hours and so on. The unit of the rate constant is
