What is the physical significance of the constant q

Chemical reactions obey a relationship between reaction ratek and activation energy ΔG^‡ that canbe written k =Qexp(-ΔG^‡/RT)whereQ is a constant characteristic of the reaction,R is the gas constant, 0.001986 kcal/(mol-deg), andT is the Kelvin temperature. The activation energyΔG^‡ for a particular uncatalyzedreaction is 15 kcal/mol and the overall difference in energybetween reactants and products ΔG⁰ is0.

(a) By what factor will the reaction rate change if we increase thetemperature from 300K to 360K?
(b) An enzyme catalyzes the reaction so that the enzymatic reactionhas a ΔG^‡ = 5 kcal/mol. By what factor will the reaction rate increase at 300K if we compare the catalyzed reaction to the uncatalyzed reaction?
(c) What is the physical significance of the constant Q in the front of this equation?
