Identify the reaction order from each of the following rate constants.
$(i)$ $k = 2.3 \times 10^{-5} \, L \, mol^{-1} \, s^{-1}$
$(ii)$ $k = 3 \times 10^{-4} \, s^{-1}$

• A
  $i$ is second order,$ii$ is first order
• B
  $i$ is first order,$ii$ is second order
• C
  $i$ is zero order,$ii$ is first order
• D
  $i$ is second order,$ii$ is zero order
