(A) The rate law is given by $-\frac{d[HI]}{dt} = k[HI]^2$. Here,the rate of reaction has units of concentration per unit time,i.e.,$mol \ L^{-1} \ s^{-1}$. The concentration $[HI]$ has units of $mol \ L^{-1}$. Substituting these into the rate law: $mol \ L^{-1} \ s^{-1} = k \times (mol \ L^{-1})^2$. Therefore,$k = \frac{mol \ L^{-1} \ s^{-1}}{(mol \ L^{-1})^2} = (mol \ L^{-1})^{-1} \ s^{-1} = L \ mol^{-1} \ s^{-1}$.
