Answer to Question #158320 in General Chemistry for kali

Question

Write the equilibrium constant expressions for the following reactions. and show steps on how to do it, please.

PCl 5(g)<=> PCl 3(g)+ CI 2(g)

Cu (OH)2(s)<=> Cu^2++ 20H^-(aq)

[Cu (NH3)4]^2+<=>Cu^2++ 4NH3(aq)

CH3 CH2 CH2COOH(aq)+ H2O (l)<=>CH3 CH2 CH2COO-(aq)+ H3O^+(aq)

Answer 1

In the chemical equilibrium constant expression, it is ratio of

concentration of products to concentration of reactant raised to power stoichometric coefficients.

And we can't include solids and liquids.

A) K = [PCl3][Cl2]/[PCl5]

B) K = [Cu²⁺][OH^-]²

C) K = [Cu²⁺][NH₃]⁴/[Cu(NH₃)₄]²⁺]

D) K = [CH3CH2CH2COO^-][H₃O+]/[CH3CH2CH2COOH]
