respect to $C{l}_2$If the units for rate are $\frac{M}{m}in,$ what are the units of the rate constant for this reaction?

A$)$ min$*M^{\frac{3}{2}}$

C$)\frac{1}{\text{m}\text{i}\text{n}*M^{\frac{7}{2}}}$

B$)\frac{1}{\text{m}\text{i}\text{n}*M^{\frac{5}{2}}}$

D$)mi\frac{n}{M^{\frac{3}{2}}}$

E$)\frac{1}{\text{m}\text{i}\text{n}*M^{\frac{3}{2}}}$

The reaction $D$ Products is first order, and the rate constant is $2\mathrm{.}7{10}^{-4}{s}^{-1}.$ If the initial

concentration of D is $3\mathrm{.}00M,$ then what is the final concentration of $D$ after $2\mathrm{.}50hr?$

A$)2\mathrm{.}9M$

B$)2\mathrm{.}4M$

C$)1\mathrm{.}0M$

D$)0\mathrm{.}26M$

E$)3\mathrm{.}0M$
