Question

What happens when the temperature of a reaction increases?

• A. The activation energy increases
• B. The rate constant increases
• C. The enthalpy change increases
• D. The order of the reaction increases

Hint:

A higher temperature leads to faster molecular movement, increasing the chances of effective collisions, which in turn increases the reaction rate.

Answer 1

The Correct Option is B

Increasing the temperature generally increases the rate constant of a reaction, as per the Arrhenius equation, which shows that the rate constant increases exponentially with temperature. This leads to an increased rate of reaction. Thus, the correct answer is (b).
