Given that `:`
`2CO_((g))+O_(2(g))rarr2CO_(2(g)),DeltaH^(@)=-P kJ`
`C_((s))+O_(2(g))rarr CO_(2(g)), DeltaH^(@)=-Q kJ`
the enthalpy of formation of carbon monoxide is `:`

Given that C + O_2 rarr CO_(2) , DeltaH^@ = -xkJ 2CO + O_2 rarr 2CO_2 , DeltaH^@ = -y kJ The enthalpy of formation of carbon monoxide will be

If C(s)+O_(2)(g)rarrCO_(2)(g),DeltaH=X and CO(g)+1//2O_(2)(g)rarrCO_(2)(g),DeltaH=Y , then the heat of formation of CO is

C_((s))+O_(2(g))rarr CO_(2(g))+Q is ………………….

Given C_((s)) + O_(2(g)) rarr CO_(2(g)), Delta H = -395 kJ , S_((g)) + O_(2(g)) rarr SO_(2(g)) , Delta H = -295 kJ , CS_(2(l)) + 3O_(2(g)) rarr CO_(2(g)) + 2SO_(2(g)) , Delta H = -1110 kJ The heat of formation of CS_(2(l)) is

Given C_((s)) + O_(2(g)) rarr CO_(2(g)), Delta H = -395 kJ , S_((g)) + O_(2(g)) rarr SO_(2(g)) , Delta H = -295 kJ , CS_(2(l)) + 3O_(2(g)) rarr CO_(2(g)) + 2SO_(2(g)) , Delta H = -1110 kJ The heat of formation of CS_(2(l)) is
