What is the favorability of most exothermic reactions at equilibrium, product-favored or reactant-favored at equilibrium? How about most endothermic reactions?
Is the statement below correct? Why or why not? Briefly explain.
Product-favored reactions always have negative values of ΔH and reactant-favored reactions always have positive values of ΔH.

Many chemical reactions release energy, while others require energy to happen. These energy changes that occur during chemical reactions are due to changes in bonding between the reactant molecules and product molecules. Breaking bonds between atoms always requires energy, while creating bonds between atoms always releases energy. Analyze each of the two chemical reactions below by calculating the total amount of energy needed to break the bonds in the reactants, the total amount of energy released upon bond formation in...
