How does heat affect a chemical reaction
WebChemical reaction rates increase or decrease according to factors including temperature, pressure and light. A catalyst changes the rate of reaction but is unchanged at the end of the reaction. WebFeb 12, 2024 · How does heat affect rate of chemical reaction? Since many chemical reactions can occur at room temperature, you might assume that temperature has no bearing on whether or not a reaction will transpire. The temperature, however, greatly affects the rate of a chemical reaction.
