Consider the following reaction at \( 25^{\circ} \mathrm{C} \) :
\[
\left(\mathrm{CH}_{3}\right)_{3} \mathrm{COH}(l)+\mathrm{HCl}(a q) \rightarrow\left(\mathrm{CH}_{3}\right)_{3} \mathrm{CCl}(l)+\mathrm{H}_{2} \mathrm{O}(l)
\]
The experimentally determined rate law for this reaction indicates that the reaction is of first order in \( \left(\mathrm{CH}_{3}\right)_{3} \mathrm{COH} \) and that the reaction is of first order overall. Which of the following would produce an increase in the rate of this reaction?
(a) Increasing the concentration of \( \left(\mathrm{CH}_{3}\right)_{3} \mathrm{COH} \)
(b) Increasing the concentration of \( \mathrm{HCl} \)
(c) Decreasing the concentration of \( \mathrm{HCl} \)
(d) Decreasing the concentration of \( \left(\mathrm{CH}_{3}\right)_{3} \mathrm{CCl} \)
