H20 -> H2 + O2

C6H6 + O3 -> C6H6O3

AlCl + Na -> NaCl + Al

NaCl + MgO2 -> MgCl + NaO2

Energy required to start a chemical reaction

lowers activation energy required for a reaction

the gaining of electrons during a chemical reaction

the loss of electrons during a chemical reaction

describes a chemical reaction that releases more energy than it absorbs

describes a chemical reaction whose products contain more stored energy than its reactants

When a system reaches chemical equilibrium, the forward and reverse reactions stop.
