reactions, most particles have energies greater Which one of these statements about the Boltzmann curve is correct? A A The Boltzmann curve shows that for most than the activation energy. The Boltzmann curve shows the total number of particles on the y-axis and the activation В energy on the x-axis. C When the temperature of a chemical reaction is increased the highest point on the Boltzmann curve is still the same. D At constant temperature, the area under the Boltzmann curve above the activation energy is greater for a catalysed reaction than for the same uncatalysed reaction.
