The diagram shows the Maxwell-Boltzmann distribution of molecular energies for a gas-phase reaction at temperature T1T_1T1, where Ea E_a\,Ea is the activation energy of the reaction.
The temperature of the system is increased to T2T_2T2. Which statement correctly describes the changes to the peak of the curve and the value of EaE_aEa?
The peak shifts to a higher energy, its height increases, and the value of EaE_aEa remains unchanged.
The peak shifts to a higher energy, its height decreases, and the value of EaE_aEa remains unchanged.
The peak shifts to a lower energy, its height decreases, and the value of EaE_aEa decreases.
The peak shifts to a higher energy, its height decreases, and the value of EaE_aEa decreases.
