Gunpowder Is Usually a Mixture Potassium Nitrate,graphite,and Sulfur \to 3 CO2(g)+ 3 CO(g)+ 2 N2(g)+ K2CO3(s)+ K2S(s)

Question 187

Short Answer

Gunpowder is usually a mixture potassium nitrate,graphite,and sulfur.When it explodes,carbon dioxide,carbon monoxide,nitrogen,potassium carbonate,and potassium sulfide are possible products.Determine the standard enthalpy of reaction using standard enthalpies of formation (given in kJ/mol).
4 KNO3(s)+ 7 C(s)+ S(s) \to 3 CO2(g)+ 3 CO(g)+ 2 N2(g)+ K2CO3(s)+ K2S(s) \quad Δ\Delta H° = -? kJ
KNO3(s),-494.6; CO2(g),-393.5; CO(g),-110.5; K2CO3(s),-1151.0; K2S(s),-380.7
