AP Chemistry
5.6 Reaction Energy Profile
5.5 Collision Model
A student investigates the kinetics of two gas-phase reactions, Reaction 1 and Reaction 2, that have identical frequency factors (\(A\)) but different activation energies (\(E_a\)). Reaction 1 has an activation energy of \(120\text{ kJ/mol}\), whereas Reaction 2 has an activation energy of \(25\text{ kJ/mol}\). When the temperature of both reaction mixtures is increased from \(298\text{ K}\) to \(318\text{ K}\) at constant reactant concentrations, which reaction exhibits a greater relative increase in reaction rate, and why?
