Factors That Affect the Chemical Reaction Rate - ThoughtCo

WebNov 26, 2024 · A general rule for most (not all) chemical reactions is that the rate at which the reaction proceeds will approximately double for each 10-degree Celsius increase in temperature. Once the temperature reaches a certain point, some of the chemical species may be altered (e.g., denaturing of proteins) and the chemical reaction will slow or stop.
