Reactivity example science
WebReactivity involves both the thermodynamics and kinetics of the particular chemical reaction. A reaction will be more reactive if the total energy of the products is less than the total energy of the reactants. A reaction will be more reactive if the energy of its transition is low. Lithium reacts with water and air. WebMar 25, 2024 · A familiar example of a combustion reaction is a lighted match. When a match is struck, friction heats the head to a temperature at which the chemicals react and generate more heat than can escape into the air, and they burn with a flame.
