If an endothermic reaction is at equilibrium, how will the equilibrium shift when heat is added to the reaction? View Available Hint(s) The reaction will shift toward the reactants. The reaction will shift toward the products. The reaction will not shift toward products or reactants. The reaction will shift toward both reactants and products.
