A particular chemical reaction carried out at 40°C takes 2 hours. Approximately how long will it take to carry out the reaction at 20°C?

Question

Quizplus · Accepted Answer

The rate of chemical reactions generally decreases with a decrease in temperature. According to the rule of thumb known as the Q10 rule, for many reactions, the rate of reaction decreases by half for every 10°C decrease in temperature. Therefore, if the reaction takes 2 hours at 40°C, it would take approximately 8 hours at 20°C.
