The diagram illustrates the Boltzmann distribution for the energy of gaseous molecules at one specific temperature. Which statement is correct?
- AIf the temperature of the gas is raised, the height of the maximum of the curve increases.
- BIf the temperature of the gas is raised, the maximum of the curve moves to the right.
- CThe length of the line labelled $X$ shows the activation energy for the reaction.
- DThe length of the line labelled $Y$ shows the enthalpy change of the reaction.
