Expert Solution
Step 1

1) is correct that increase in the temperature increase the total number of molecular collisions that occur this is according to the maxwell boltzmann distribution curve and the activation energy should be decreased and the rate of the reaction should increase.

2)is also correct according to the collision theory state effective collision will lead to product formation with the increase in the temperature the collisions frequency  increase with increase  in the collisions frequency also increase the percentage collisions that lead to product formation.
