The validation about the statement “Some systems at equilibrium are exothermic, and some are endothermic” is to be predicted. Concept introduction: Equilibrium is a state of a chemical reaction in which the rate of forward reaction is equal to the rate of backward reaction. The rate of change in the concentration of reactants and products becomes constant and do not change with time.
