The concentration of the NOCl in the reaction is 0.000137 mol/L.
Reaction equilibrium constant
For a given chemical reaction, the ratio of product to reactant concentrations at a state of chemical equilibrium is expressed numerically as the reaction equilibrium constant.
The location of the equilibrium and the proportions of reactants and products at that point are both revealed by the equilibrium constant.
