Higher order $(>3)$ reactions are rare due to

$(a)$ Write the general reaction and derive the units of the rate constant. $(b)$ Based on that,write the rate constant units for zero,first,and $2^{nd}$ order reactions.

The rate equation for the reaction $2 A + B \longrightarrow$ products is $\text{rate} = k[A][B]^2$. If $k$ at $T \ K$ is $5.0 \times 10^{-6} \ mol^{-2} \ L^2 \ s^{-1}$,the initial rate of the reaction,when $[A] = 0.05 \ mol \ L^{-1}$ and $[B] = 0.1 \ mol \ L^{-1}$ is:

The reaction $2N_2O_5 \rightleftharpoons 2N_2O_4 + O_2$ is

Which of the following is an example of a pseudo unimolecular reaction?

The alkaline hydrolysis of an ester is a .......
