High rate constant

Webrate = k[A]m[B]n in which [ A] and [ B] represent the molar concentrations of reactants, and k is the rate constant, which is specific for a particular reaction at a particular temperature. The exponents m and n are the reaction orders and are typically positive integers, though they can be fractions, negative, or zero. Webyou can see that the rate constant increases for an increase in temperature (and as activation energy increases, the rate constant decreases. Now, since the rate constant increases, this implies that the rate of reaction increases with temperature. Regarding concentration: you are correct in that concentration affects the rate of reaction.
