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 an effective catalyst is added to the mixture?
Options
A The height of the peak decreases and the activation energy moves to the right.
B The height of the peak decreases and the activation energy moves to the left.
C The height of the peak remains the same and the activation energy moves to the right.
D The height of the peak remains the same and the activation energy moves to the left.
