Question

Given two temperatures, 39 °F and 51 °F, which of the following correctly compares the number of chances for particles to bounce off each other during a chemical reaction?

Same at both
Lower at 51 °F
Lower at 39 °F
Does not depend on temperature

Answer 1

Lower at 39 •F

Explanation:

Answer 2

The answer to this question would be:
Lower at 39 °F

The kinetic energy of a molecule is influenced by temperature. Higher temperature will result in higher kinetic energy which means the molecule moves at a higher velocity. This will increase the chance of the chemical reaction. That is why the rate of reaction will be higher at the higher temperature. Then, a lower temperature will mean a lower speed too.
