How temperature affects chemical change
NettetThe affect temperature has on a reaction, and which side is favored, depends on its enthalpy, whether it is exothermic or endothermic. If a reaction is exothermic, more energy is being lost by the system than is being input. So, we can think of the enthalpy in an exothermic reaction as a product.

Mathematically, this will alter the … NettetAs the temperature increases, the reactant molecules gain energy and move faster. The faster the molecules are moving, the more likely they are to collide and the greater the frequency of collisions will be. The higher the temperature, the greater the frequency of collisions between molecules.
