Reaction kinetics — practice question

The diagram illustrates a Boltzmann distribution curve. The axes have not been labelled. X and Y are points on the vertical axis. What is shown by both X and Y?

  • 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
