The Maxwell-Boltzmann distribution curves below represent the kinetic energies of molecules at four different temperatures in a reaction with an activation energy, Ea, of 7 arbitrary units-used to study kinetics of this reaction at these four temperatures. Amount of the reactant is different at each temperature.Select the perfectly valid statement(s) useful in the study of kinetics of the reaction at different temperatures in terms of Arrhenius collision theory without considering Steric factor:
