Question

Q 77 On increasing the temperature, the rate
of a chemical reaction:
Ops: A.
O decreases
B.
O either increases or decreases
C.
O remains constant
D.
O increases​

Answer 1

Answer:

Increasing the temperature increases reaction rates because of the disproportionately large increase in the number of high energy collisions. It is only these collisions (possessing at least the activation energy for the reaction) which result in a reaction.

Answer 2

Answer:

increases (D)

Explanation:

Increase in temperature generally lowers the activation energy of the reaction.

Increasing the temperature will not always increase the rate of the reaction. If the temperature of a reaction were to reach a certain point where the reactant will begin to degrade, it will decrease the rate of the reaction.

Increasing the temperature increases reaction rates
