Reaction kinetics — practice question

The diagram illustrates the Boltzmann distribution for the energies of particles in a gas. This gas may undergo a reaction with an activation energy, $E_a$. The gas is kept at a fixed temperature. Which of the statements is correct?

  • AIf a catalyst is added, peak P will be lower and $E_a$ will move to the left.
  • BIf a catalyst is added, peak P will be lower and $E_a$ will move to the right.
  • CIf a catalyst is added, peak P will be the same and $E_a$ will move to the left.
  • DIf a catalyst is added, peak P will be the same and $E_a$ will move to the right.
