Determine DeltaH for the following reaction at 500 K and constant pressure : CO(g)+H_(2)O (g) rarr CO_(2) (g) +H_(2)(g) Use the following data : {:("Substance",C_(P)" (J/mol K)",Delta_(f)H (298 K) "(kJ/mol)"),(CO,29.12,-110.5),(H_(2)O,33.58,-241.8),(CO_(2),37.11,-393.5),(H_(2),29.89,0.0):}

Answer»


SOLUTION :Apply `DeltaH_(2)-DeltaH_(1)=DeltaC_(P) [T_(2)-T_(1)] RARR 'DeltaH_(2)=-40.3" kJ mol"^(-1)`
