Answer to Question #159982 in General Chemistry for Bassie Moeng

Question

Write the indicated equilibrium expression for the following:

1) Kc : Cd2+(aq) + 4 Br-(aq) ↔ CdBr4 2-(aq)

2) Kp : CH4(g) + 2 H2S (g) ↔ CS2(g) + 4 H2 (g)

3) Kc : Ca3(PO4)2(s) ↔ 3 Ca2+ (aq) + 2 PO4 3-(aq)

4) Kp : CO2(g) + H2(g) ↔ CO (g) + H2O (l)

5) Kc : Ti (s) + 2 Cl2(g) ↔ TiCl4(l)

Answer 1

1) K_c =[CdBr₄^2-]/[Br^-]⁴[Cd²⁺]

2) K_p =(P_CS2)•( P_H2)⁴/(P_CH4) • (P_H2S)²

3) K_c = [Ca²⁺]³[PO₄^3-]²

4) K_p = P_CO/P_CO2 •P_H2

5) K_c = [Cl₂]²
