Glass calorimeter is used to determine:
Correct answer: A. ∆H°n
- A. ∆H°n
- B. ∆H°at
- C. ∆H°sol
- D. ∆H°f
Explanation
Option A, "∆H°n," is correct because a glass calorimeter is typically used to measure the heat of a chemical reaction at constant pressure, which is represented by the symbol ∆H°. This value is known as the standard enthalpy change of reaction. It gives us information about the heat exchange that occurs during a chemical reaction under standard conditions.

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
