(a)

Interpretation Introduction

Interpretation:

The balanced formation equation for CH3OH(l) is to be written. Also, the corresponding value of ΔHf° for CH3OH(l) is to be included.

Concept introduction:

The standard enthalpy of formation (ΔHf°) is the enthalpy change of the formation of 1mol of compound from its elements and the reactants and products in this case is also present in their standard state.

Standard state includes 1atm pressure for gases, 1M concentration for substances in aqueous phase and the most stable form of substance at 1atm pressure and 298K tempertaure. For example, metal like sodium exist in solid state and molecular elements like halogen exist in gaseous state.

(b)
