A chemistry student needs to determine the effect of increasing temperature on the equilibrium position of a chemical reaction in which an exothermic reaction is taking place. Given the balanced chemical equation A + B ⇌ C + heat, the student needs to determine how the concentration of products and reactants will change as the temperature is increased, and explain the observed changes using Le Chatelier's principle.
