The diagram shows the Boltzmann distribution of energies in a gas. The gas undergoes a reaction with an activation energy, . The peak of the distribution is labelled P.
If the same reaction is carried out in the presence of a catalyst, which statement is correct?
Options
A The peak P is at a lower height and the position of moves to the left.
B The peak P is at a lower height and the position of moves to the right.
C The peak P remains at the same height and the position of moves to the left.
D The peak P remains at the same height and the position of moves to the right.
