WebWhat leads to a high rate constant (fast rate)? a. A high activation barrier and high temperature b. A high activation barrier and low temperature c. A low activation barrier and high temperature d. A low activation barrier and low temperature 10. 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.
For an elementary step, there is a relationship between stoichiometry and rate law, as determined by the law of mass action. Almost all elementary steps are either unimolecular or bimolecular. For a unimolecular step the reaction rate is described by , where is a unimolecular rate constant. Since a reaction requires a change in molecular geometry, unimolecular rate constants cannot be larger than the frequency …
