The minimum amount of energy needed for colliding particles to react is called
Chemical Energy
Kinetic Energy
Activation Energy
Potential Energy
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
What happens to the energy in this reaction.
The energy needed for the reaction to occur is higher than the energy of the produced by the reaction.
The energy produced is higher than the energy needed for the reaction to occur.
