Calculate the work performed when 2 moles of hydrogen expand isothermally and reversibly at 25ºC form 15 to 50 litres.

The ∆H_f0 for CO₂(g), CO(g) and H₂O (g) are –393.5, –110.5 and –241.8 kJ mol^–1 respectively. The standard enthalpy change (in kJ) for the reaction CO₂(g) + H₂(g) → CO(g) + H₂O (g) is –

For reaction carried out in automobiles, what is the value of ∆H, ∆S and ∆G ? 2C₈H₁₈(g) + 25O₂(g) 16CO₂(g)+ 18H₂O(g)

The conversion A to B is carried out by the following path :
Given : ∆S(A → C) = 50 e.u. , ∆S(C → D) = 30 e.u. , ∆S(B → D) = 20 e.u.
Where e.u. is entropy unit then ∆S(A → B) is
