How does heat affect a chemical reaction
WebChemical reactions typically occur faster at higher temperatures. Food can spoil quickly when left on the kitchen counter. However, the lower temperature inside of a refrigerator slows that process so that the same food remains fresh for days. WebJul 3, 2024 · Explanation: An increase in heat energy means an increase in temperature, which also increases the average kinetic energy of the molecules in the process. This means that there are more collisions and higher frequency of successful collisions between the reactants during the reaction, therefore speeding up the chemical reaction. A cool lab to ...
