Total questions: 12
Worksheet time: 12mins
Why does a higher concentration increase the rate of reaction?
it increases the amount of reactants
it lowers the activation energy
it increases the energy of particle collisions
it increases the frequency of particle collisions
Why does a higher temperature increase the rate of a reaction?
it increases both the frequency and energy of particle collisions
it only increases the frequency of particle collisions
it only increases the energy of particle collisions
it reduces the activation energy of the reaction
