Which factor can decrease the rate of a chemical reaction? a. low activation energy b. high pressure c. low temperature d. high concentration of reactants

Low temperature

Explanation:

Any chemical reaction works best at high temperature because the molecules will have high kinetic energy which allows them to collide and reaction will occur fast.

In case of low temperatures( cold temperature) the molecules will have less kinetic energy and they would not collide and the reaction will not take place.

So, low temperatures decreases the rate of chemical reaction.
