Problem
For a single Maxwell–Boltzmann distribution of molecular kinetic energies, a vertical line on the energy axis is drawn at the activation energy Ea for a particular reaction.
Which region of the diagram represents the molecules that have sufficient energy to react?
(a) The entire area under the curve, because molecules continually collide and eventually react
(b) Only the molecules whose energies lie near the peak of the distribution
(c) The area under the curve to the right of Ea
(d) The area under the curve to the left of Ea
