Reaction kinetics — practice question

A Boltzmann distribution for a sample of reacting gas at constant temperature is shown. The activation energy, $E_A$, for the reaction is indicated. Point \times indicates the number of particles whose energy equals the activation energy. The temperature of the gas sample is reduced. The form of the distribution curve changes. Which point could represent the number of particles whose energy is equal to the activation energy at the lower temperature?

  • APoint A
  • BPoint B
  • CPoint C
  • DPoint D
