At a certain temperature, the equilibrium constant for the chemical reaction shown is 1.60×10−3 . At equilibrium, the concentration of AB is 1.825 M, the concentration of BC is 1.625 M, and the concentration of AC is 0.130 M. Calculate the concentration of B at equilibrium. AB(aq)+BC(aq)↽−−⇀AC(aq)+2B(aq) AB ( aq ) + BC ( aq ) ↽ − − ⇀ AC ( aq ) + 2 B ( aq ) [B] =

Thus the concentration of B at equilibrium is 0.191 M

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as

For the given chemical reaction:

The expression for is written as:

Thus the concentration of B at equilibrium is 0.191 M
