Answer» Solution :(i) `DeltaG^(@) = - 394.36 - [ -137.17 -228.57]` `= - 28.62` `= - 2.303 RT logK_(p)` `K_(p)= 1.047 xx 10^(5)` `By ""H_(2)O(L) hArr H_(2)O(g)` `DeltaG^(@) = - 228.57 + 237.13` ` = 8.56 = RT InK_(p)` `K_(p) = 0.0316 "BAR"` `P_(H_(2)O) (g) = 3.16pa` `underset("at eq.pressureX") underset("Initial pressure (101.325)")(CO) + underset(3.16 KPA)underset((3.16 kpa))(H_(2)O(g))""hArr""underset(202.65 kpa)underset((101.325))(CO_(2)) + underset(202 .65 kpa)underset((101.325))(H_(2))` `1.047 xx 10^(5) =(202.65)^(5)/(X xx3.16)` `X = 0.124kPa`
