Q
rate increased with temp. explain why this is the case in terms of collisions
A
as you increase temperatures, the amount of energy will increase and become greater than the activation energy. this will then increase the number of successful collisions
2
Q
an example of a catalyst
A
MNO2 - manganese dioxide
3
Q
how does a catalyst increase rate of reaction
A
adding a catalyst will provide a different pathway for a reaction with a lower Ea. Now that the energy is greater than the activation energy, more collisions will occur so the rate will increase
