Answer to Question #204769 in Chemistry for Master j

Question

Write the equilibrium expressions for K_c and K_p for each of the following reactions:

i. H₂(g) + F₂(g) ⇌ 2HF (g)

ii. Zn(s) + 2HCl(aq) ⇌ ZnCl₂(aq) + H₂(g)

Answer 1

i. K_c = [HF]² / [H₂] [F₂]

K_p = P(HF)² / P(H₂) P(F₂)

ii. K_c = [ZnCl₂] [H₂] / [HCl]²

K_p = P(H₂)
