Question

 Discuss the factors affecting the sign of ∆G in the relationship ∆G= ∆H - T∆S. Give examples for each of the situations.

Answer 1

At low temperature: +, at high temperature: -  2HgO(s) -> 2Hg (l) + O2 (g)

At all temperature: +     3O2 (g) ->2O3 (g)

At all temperature: -      2H2O2 (l) -> 2H2O (l) + O2 (g)

At low temperature: - , at high temperature: + NH3 (g) + HCl (g) -> NH4Cl (s)
