Given that `(1)/(2)S_(8)(s)+6O_(2)(g)to4SO_(3)(g)`, `DeltaH^(@)=-1590 kJ`
The standard enthalpy of formation of `SO_(3)` is

Given that (1)/(2)S_(8(s)) + 6O_(2(g)) rarr 4SO_(3(g)), Delta H^(0) = - 1590kJ . The standard enthalpy of formation of SO_(3) is

Consider the reaction : SO_(2)(g)+(1)/(2)O_(2)(g) rarr SO_(3)(g),DeltaH=-98.3kJ If the enthalpy of formationof SO_(3)(g) is -395.4kJ , then the enthalpy of formation of SO_92)(g) is

Delta H for the reaction, SO_(2) (g) + (1)/(2) O_(2)(g) hArr SO_(3)(g) " " Delta H = -98.3kJ If the enthalpy of formation of SO_(3)(g) is -395.4kJ, then enthalpy of formation of SO_(2)(g) is:

The Delta H^(theta) for the reaction 4S(s) + 6O_(2)(g) rarr 4 SO_(3)(g) is -1583.2kJ . Standard enthalpy of formation of sulphur trioxide is:

C(s)+(1)/(2)O_(2)(g)toCO(g),DeltaH=-110.4kJ . Does this DeltaH represent enthalpy of combustion of carbon?

4S(s)+60_2to4SO_(3)(g),DeltaH f or this reaction is - 1583.2 kJ . The enthalpy of formation of sulphur trioxide is -

Given C(s)+O_(2)(g)toCO_(2)(g) , DeltaH=-395 kJ S(s)+O_(2)(g)toSO_(2)(g) , DeltaH=-295 kJ CS_(2)(l)+3O_(2)(g)toCO_(2)(g)+2SO_(2)(g) , DeltaH=-1110 kJ The heat of formation of CS_(2)(l) is

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 :

4S(s)+60to4SO_(3)(g),DeltaH f or this reaction is - 1583.2 kJ . The enthalpy of formation of sulphur trioxide is -
