Reaction kinetics — practice question

The diagram illustrates a Boltzmann distribution for the molecular energies in a gaseous mixture. The distribution has a maximum, marked $P$ on the diagram. What occurs when the temperature of the mixture rises?

  • AThe height of the peak, $P$, decreases and the activation energy moves to the left.
  • BThe height of the peak, $P$, decreases and the activation energy moves to the right.
  • CThe height of the peak, $P$, decreases and the activation energy does not change.
  • DThe height of the peak, $P$, increases and the activation energy moves to the left.
