Question

What are the guidline for writing a thermochemical equation?

Answer 1

Hey,

•If a certain process has an enthalpy change DH, the reverse of that process has an enthalpy change of -DH.

•Multiplying a thermochemical equation by a constant also multiplies the thermodynamic quantity by that constant.

•The thermodynamic quantity for the reaction applies as the equation is written. So, it can be used as a stoichiometric ratio with any of the reactants or products in the reaction.

Answer 2

Guidelines of writing the thermochemical equation:

•  If an explicit method has an enthalpy change of H, then the reverse of that method has an enthalpy change of -H.

• When we multiply a thermochemical equation by a constant also increases the quantity of thermodynamic by that constant.

• The thermodynamic amount for the reaction applies as the equation. Therefore, it can be used as a stoichiometric relation with any of the reactants or products in that reaction
