Vedclass · Answer

(A) The general unit for the rate constant $k$ of an $n^{th}$ order reaction is given by the formula: $(mol \cdot L^{-1})^{1-n} \cdot time^{-1}$.For a first-order reaction $(n=1)$: Unit $= (mol \cdot L^{-1})^{1-1} \cdot time^{-1} = time^{-1}$.For a second-order reaction $(n=2)$: Unit $= (mol \cdot L^{-1})^{1-2} \cdot time^{-1} = (mol \cdot L^{-1})^{-1} \cdot time^{-1} = mol^{-1} \cdot L \cdot time^{-1}$.Thus,the units are $time^{-1}$ and $mol^{-1} \cdot L \cdot time^{-1}$ respectively.

The rate constants for first-order and second-order reactions have units of ..... respectively.

For a reaction $2 \ A + B \rightarrow P$, when the concentration of $B$ alone is doubled, the rate does not change, and when the concentrations of both $A$ and $B$ are doubled, the rate increases by a factor of $4$. The unit of the rate constant is,
