Question

Calculate the equilibrium constant for the chemical reaction, given the equilibrium concentrations of the reactants and products in the table.

2AB(aq)+4CD(aq)↽−−⇀2AD(aq)+2BD(aq)+4C(aq)

SubstanceEquilibrium concentration
AB	3.543.54 M
CD	4.844.84 M
AD	4.054.05 M
BD	2.692.69 M
C	2.652.65 M

Answer 1

The Keq expression for this reaction can be written as:

K_eq = [AD²][BD]²[C]⁴ / [AB]²[CD]⁴

Now just plug in the equilibrium concentrations to calculate K_eq
