In a chemical system the particles involved have a range of energies. This can be shown on a graph called the Boltzmann distribution. Which statement correctly explains the effect of a catalyst on the particles in a chemical system?
Acatalyst enables particles with a lower energy to collide successfully.
Bcatalyst increases the number of particles with higher energies.
Ccatalyst increases the number of particles with the most probable energy value.
Dcatalyst increases the value of the most probable particle energy.
✓ Correct answer
A: catalyst enables particles with a lower energy to collide successfully.
