Reaction kinetics — practice question

The diagram depicts a Boltzmann distribution curve, and the axes have no labels. X and Y are points on the vertical axis. What do X and Y both represent?

  • Apoint X: number of molecules with energy equal to $E_A$; point Y: largest number of molecules with the same energy
  • Bpoint X: number of molecules with energy equal to or greater than $E_A$; point Y: largest number of molecules with the same energy
  • Cpoint X: number of molecules with energy equal to $E_A$; point Y: the amount of energy of the greatest number of molecules
  • Dpoint X: number of molecules with energy equal to or greater than $E_A$; point Y: the amount of energy of the greatest number of molecules
