... 1. If a reaction is reversed, the sign of ΔH is also reversed. 2.The magnitude of ΔH is directly proportional to the quantities of reactants and products in a reaction. If the coefficients in a balanced reaction are multiplied by integer, the value of ΔH is multiplied by the same integer. Xe(g) + 2F ...
