Predict whether the equilibria
I) CO2(g) + 2NH3(g) =
CO(NH2)2(s) + H2O(g),
AH° = -90 kJ
II) Ni(s) + 4CO(g) = Ni(CO)4(g),
AH° = –161 kJ
will shift toward products or reactants with a
temperature increase.
1. I shifts toward reactants and II shifts
toward products.
2. Both I and II shift toward products.
3. Unable to determine
4. Both I and II shift toward reactants.
5. I shifts toward products and II shifts to-
ward reactants.
