Comprehension Level 2 (medium)

Match the following

• Enthalpy change of Formation

• Enthalpy change of solution

• Enthalpy change of combustion

• Enthalpy change of neutralisation

• Enthalpy change of vaporization

Charlotte is studying the Hess cycle in her chemistry class. What are the main components of Hess cycle?

• Enthalpy changes of individual steps, overall enthalpy change, and the reaction path.

• Pressure changes in the reaction

• Temperature changes of individual steps

• Catalyst effects on the reaction path

For a data like shared in the question, mention steps how to calculate final answer. You are not supposed to calculate. just mention step-by-step manner how to get to the final answer. and also mention unit for final answer.

For the given question, suggest what would be direction arrows in fully drawn Hess cycle (towards reactants and products or away or mix), if available data is for enthalpy change of formation. it is appreciated if complete cycle is drawn and uploaded.
