Increasing the temperature of the reactants increases the fraction of the reacting species that collide with energies equal to or greater than the free energy/activation energy. Another factor that can affect whether or not molecules react is their orientation/bond length toward one another when they collide. Molecules with incorrect bond lengths/orientations will not react even if they successfully collide.
