The diagram shows the Boltzmann distribution of energies in one mole of a gas. The gas takes part in a reaction with an activation energy, .
Boltzmann energy distribution for one mole of gas: number of particles (vertical axis) against energy (horizontal axis), a curve rising from the origin to a peak labelled P then falling and tailing off toward high energy; a dashed vertical line marks the activation energy $E_a$ on the energy axis, to the right of the peak.
Which statement correctly describes the effect of an increase in temperature?
