The diagram shown below shows, at a fixed temperature, the Boltzmann distribution for the kinetic energy of the molecules in a mixture of two gases that react slowly with each other. The activation energy for the reaction, $E_a$, is indicated. When the reaction is catalysed, the reaction rate increases slightly. Where will $E_a$ be for the catalysed reaction?
