WebApr 19, 2012 · What is the difference between Reactants and Products? • Reactants are the substances consumed during a reaction and products are formed. • So reactants can be seen before a reaction whereas products are available after a reaction. (Sometimes unreacted reactants can also be present after a reaction.) WebChemical equilibrium: A state in which the rates of the forward and reverse reactions are equal and the concentrations of the reactants and products remain constant. products to reactants are still going on, although there is no net change in the number of reactant and product molecules. For the reaction: N 2O 4(g) 2NO 2(g) The Equilibrium Constant
