Calculate `DeltaG` for the reaction at `25^(@)C` when partial pressure of reactants `H_(2)`, `CO_(2)`, `H_(2)O` and `CO` are `10`, `20`, `0.02` and `0.01atm` respectively.
`H_(2(g))+CO_(2(g))hArrH_(2)O_((g))+CO_((g))`
Given `G_(f)^(@)` for `H_(2(g))`, `CO_(2(g))`, `H_(2)O_((g))` and `CO_((g))` are `0`, `-394.37`, `-228.58`, `-137.15 KJ` respectively.
