In the diagram, $X$ shows the Boltzmann distribution for the particle energies in a reaction, and $E_{a1}$ represents the activation energy for that reaction. Which statement is correct?
- A$E_{a2}$ is the activation energy at a higher temperature.
- B$E_{a2}$ is the activation energy at a lower temperature.
- C$Y$ is the Boltzmann distribution at a lower temperature.
- D$Z$ is the Boltzmann distribution at a higher temperature.
