A.) For which reaction will Kp = Kc?
| 2 H2O(l) ↔ 2 H2(g) +O2(g) |
| 2 HgO(s) ↔ Hg(l) + O2(g) |
| S(s) + O2(g) ↔ SO2(g) |
| H2CO3(s) ↔ H2O(l) +CO2(g) |
| CaCO3(s) ↔ CaO(s) + CO2(g) |
B.) How does an increase in the pressure within the container bythe addition of the inert gas E affect the amount of C present atequilibrium for the following reaction?
A(g) + 3 B(g) ↔ 2 C(g) +D(g)          ΔH° = -65 kJ
| The amount of C will increase. |
| The amount of C will not change. |
| Cannot be predicted. |
| The amount of C will decrease. |
C.) Which statement is true for the following reaction atequilibrium at 25°C?

| Concentration of HBr is low. |
| The forward reaction does not happen. |
| The rate of the reaction is very slow. |
| Concentration of H2 and Br2 are low. |
D.) If the temperature isincreased and some oxygen is removed, how does this affect theamount of the Cl2 present at equilibrium for the followingreaction?

| Cannot be predicted. |
| The amount of Cl2 will not change. |
| The amount of Cl2 will increase. |
| The amount of Cl2 will decrease. |
