The diagram presents the Boltzmann distribution of energies in a gas. The gas reacts with an activation energy, $E_a$. The maximum of the distribution is marked P. If the same reaction is done in the presence of a catalyst, which statement is correct?
- AThe peak P is at a lower height and the position of $E_a$ moves to the left.
- BThe peak P is at a lower height and the position of $E_a$ moves to the right.
- CThe peak P remains at the same height and the position of $E_a$ moves to the left.
- DThe peak P remains at the same height and the position of $E_a$ moves to the right.
