Write the equilibrium constant expression for each of the following reactions in terms of concentrations. (a) CO2(g) + C(s) ⇄ 2 CO(g) (b) [Cu(NH3)4)2+(aq) ⇄ Cu2+(aq) + 4 NH3(aq) (c) CH3CO2H(aq) + H2O(ℓ) ⇄ CH3CO2−(aq) + H3O+(aq)

(a)

Interpretation Introduction

Interpretation: The equilibrium constant expression for the reaction has to be written.

Concept Introduction: At equilibrium the concentration of the reaction and the product is equated to a constant K, where K is known as the equilibrium

If a reaction is as aA+bBcC+dD ,

The equilibrium constant K=[C]c[D]d[A]a[B]b

Explanation

The product concentrations appear in the numerator and reactant concentrations appear in the denominator...

Concept Introduction: At equilibrium the concentration of the reaction and the product is equated to a constant K, where K is known as the equilibrium

If a reaction is as aA+bBcC+dD ,

The equilibrium constant K=[C]c[D]d[A]a[B]b
