a. $∆{\mathrm{G}}^{°}$is the approximate reversible work done by a closed thermodynamic system. Hence, the $∆\mathrm{G}°$only determines the reversible work. $∆\mathrm{G}°$does not affect the rate of the reaction.

b. $∆\mathrm{H}°$is the value of the difference in energies of products and reactants. Hence, $∆\mathrm{H}°$does not affect the rate of the reaction.

c. ${\mathrm{E}}_{\mathrm{a}}$is the minimum energy required for reactants to undergo a chemical reaction. Hence, ${\mathrm{E}}_{\mathrm{a}}$affects the rate of reaction.

d. An increase and decrease in temperature may affect the speed at which the reacting molecules interact. Hence, temperature affects the rate of reaction.

e. The more the concentration of reactants, the more the molecules in the solution undergo a chemical reaction. This factor affects the concentration factor, the pressure factor, and the temperature factor. Hence, this factor also affects the rate of reaction.

f. ${\mathrm{K}}_{\mathrm{eq}}$does not affect the rate of the reaction.

g. K affects the rate of the reaction.

h. Catalysts add to the speed of the reaction, hence, they affect the rate of the reaction.
