A.) For which reaction will K_p = K_c?
2 H₂O(l) â†” 2 H₂(g) +O₂(g)
2 HgO(s) â†” Hg(l) + O₂(g)
S(s) + O₂(g) â†” SO₂(g)
H₂CO₃(s) â†” H₂O(l) +CO₂(g)
CaCO₃(s) â†” 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) â†” 2 C(g) +D(g)Â Â Â Â Â Â Â Â Â Â Î”HÂ° = -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 25Â°C?

H₂(g) + Br₂(g) â‡Œ2HBr(g); K = 1.9 Ã— 10¹⁹
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?
4 HCl(g) + O₂(g) â†” 2 H₂O(g) + 2Cl₂(g)Â Â Â Â Â Â Â Â Â Â Î”HÂ° = 120 kJ
Cannot be predicted.
The amount of Cl₂ will not change.
The amount of Cl₂ will increase.
The amount of Cl₂ will decrease.
