Question

$5A\to$ Product
In the above reaction, the half-life period is directly proportional to the initial concentration of reactant. The initial rate of reaction is $400mol$ ${lit}^{-1}$ ${min}^{-1}$. What is the order of reaction?

Answer 1

In a zero order reaction the half life period is directly proportional to the initial concentration of the reaction and inversely proportional to the rate constant. So the given reaction is zero order reaction.
