1.	Calculate the standardenthalpy of formationof SO_(3) at 298 K using the following reactions and enthalpies S_(8) (s) + 8 O_(2) (g) rarr 8SO_(2)(g) , DeltaH^(@) = - 2775kJ mol^(-1) 2SO_(2) (g) + O_(2)(g) rarr 2SO_(3)(g), DeltaH^(@) = - 198 kJ mol^(-1)
Answer» Solution :AIM `: (1)/(8) S_(8)(s) + (3)/(2) (G) rarr SO_(3) ,DeltaH = ?`
