35\,^{\circ}\text{C}

four different reactions were studied. The measured rate expressions and the corresponding numerical values of the rate constant are listed in the table below. However, the units of the rate constant were accidentally omitted during transcription.

Reaction	Empirical rate law	$k$ (numerical value)
1	$k_{1}[\text{F}]^{2}$	$6.7\times10^{2}$
2	$k_{2}[\text{G}]^{1/2}$	$4.5\times10^{-3}$
3	$k_{3}[\text{H}][\text{I}]$	$1.8$
4	$k_{4}$	$9.2\times10^{-5}$

(a) Determine units for each

k

\text{mol}\,\text{L}^{-1}\,\text{s}^{-1}

rate format. (b) Convert units of

k_{2}

and

k_{4}

to hour-based units. (c) Identify flagged rate constants with justification.
