What is a thermochemical equation?
If the enthalpy of reaction for A → B is -50 kJ, what is the enthalpy for 2A → 2B?
If a forward reaction has an enthalpy of -60 kJ, what is the enthalpy of the reverse reaction?
Given the reactions: 1) A + B → C, ΔH = 100 kJ; 2) C → D, ΔH = -50 kJ; 3) D → E, ΔH = 30 kJ. What is the overall enthalpy change for A + B → E?
