rates

Question 1

rate increased with temp. explain why this is the case in terms of collisions

Answer 1

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

Question 2

an example of a catalyst

Answer 2

MNO2 - manganese dioxide

Question 3

how does a catalyst increase rate of reaction

Answer 3

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
