1. Known to the following reaction:
Fe
^ (3 +) (aq) + SCN ^ - (aq) ⇌ 〖Fe (SCN)〗 ^ (2 +) (aq)
Estimate
the equilibrium shifts toward equilibrium if it:
Fe3
+ ions are added
Added
ion-HPO42
Explain!
2. Notice the following equilibrium reaction:
2NO2
(g) ⇌ N2O4 (g) ΔH = -58.8 kJ
If
the system into equilibrium temperature and pressure were enlarged, explain
what happened?
3. 2NO2 (g) ⇌ N2O4 (g) ΔH =
-59.8 kJ
At
this equilibrium, helium gas was added until the total pressure of twice the
original pressure, explain what happens at equilibrium?
