The diagram shows a Boltzmann distribution of molecular energies for a gaseous mixture. The distribution has a peak, labelled P on the diagram.
What happens when the temperature of the mixture increases?
Options
A The height of the peak, P, decreases and the activation energy moves to the left.
B The height of the peak, P, decreases and the activation energy moves to the right.
C The height of the peak, P, decreases and the activation energy does not change.
D The height of the peak, P, increases and the activation energy moves to the left.
