Which of the following relationship isincorrect?
Correct answer: C. Delta*H_{f} > Delta*H_{r}
- A. Delta*H_{v} > Delta*H_{f}
- B. Delta*H_{s} > Delta*H_{f}
- C. Delta*H_{f} > Delta*H_{r}
- D. Delta*H_{x} > Delta*H_{v}
Explanation
deltaHf is less than deltaHr because in formation only specific product with one mole forms but in reaction all type of reaction are involved

About Enthalpy
Enthalpy is the heat content of a system measured at constant pressure, and its change indicates whether a reaction or physical process is endothermic or exothermic. The topic covers state functions, enthalpy diagrams, standard enthalpy of formation, combustion and neutralisation, and the relationship between ΔH and internal energy change.
