2.8c: use, in a qualitative way, the Maxwell-Boltzmann model of the distribution of molecular energies to relate changes of concentration and temperature to the alteration in the rate of a reaction

Maxwell-Boltzmann distribution curves show us the proportion of particles with different kinetic energy values in a reactant

Eg. a higher temperature increases the rate of reaction by raising the proportion of reactant particles at or above the activation energy (E>_Ea)
