Summary :key concepts for doing enthalpy calculations• When a reaction is reversed, the magnitude of ΔHremains the same, but the sign changes.• When the balanced eq for a reaction is multipliedby an integer, the value of ΔH must be multipliedby the same integer.Copyright©2000 by HoughtonMifflin Company.
