the standard molar enthalpy of combustion of carbon (graphite)

Vedclass · Answer

(D) The standard molar enthalpy of formation of $CO_2$ corresponds to the reaction:$C_{(graphite)} + O_{2_{(g)}} \rightarrow CO_{2_{(g)}}$By definition,the enthalpy change for the combustion of one mole of a substance in its standard state is its standard molar enthalpy of combustion.Since $C_{(graphite)}$ is the standard state of carbon,the enthalpy change for this reaction is equal to the standard molar enthalpy of combustion of carbon (graphite).

Standard molar enthalpy of formation of $CO_2$ is equal to
