1.	112. Hess's law is related to:(A) Rate of reaction(B) Heat of reaction(C) Equilibrium constant(D) Effect of pressure on volume ofgas
Answer» Hess's lawallows the enthalpy change (ΔH) for a reaction to be calculated even when it cannot be measured directly. This is accomplished by performing basic algebraic operations based on the chemical equations of reactions using previously determined values for the enthalpies of formation. which option??? Use theformula∆H = m x s x ∆T to solve. Once you have m, the mass of your reactants, s, the specific heat of your product, and ∆T, the temperaturechangefrom your reaction, you are prepared to find theenthalpyof reaction. Simply plug your values into theformula∆H = m x s x ∆T and multiply to solve. first read question carefully , then answer it option b) hess law is related to heat of reaction at constant pressure
