Enthalpy is a fundamental concept in thermodynamics and refers to the heat exchange during a chemical reaction under constant pressure. Determining the enthalpy change in a chemical reaction allows ...

Hess’s Law can be used to calculate the enthalpy change for the formation of ethanoic acid from its elements. \(2C (s) + 2H_{2} (g) + O_{2} (g) \rightarrow CH_{3}COOH (l)\) Calculate the enthalpy ...
