For a reaction,doubling the concentration of the reactant doubles the half-life period. What is the order of the reaction?

The decomposition of $NH_{3}$ on a platinum surface is a zero-order reaction. What are the rates of production of $N_{2}$ and $H_{2}$ if $k = 2.5 \times 10^{-4} \, mol \, L^{-1} \, s^{-1}$?

The decomposition of $NH_3$ on a platinum surface is a zero-order reaction. What is the rate of production of $N_2$ if $k = 2.5 \times 10^{-4} \ mol \ L^{-1} \ s^{-1}$?

What is a zero order reaction? Determine the integrated rate equation for a zero order reaction $R \to P$.

The half-life for a zero order reaction having $0.02 \; M$ initial concentration of reactant is $100 \; s$. The rate constant (in $mol \; L^{-1} s^{-1}$) for the reaction is
