In a basic aqueous solution, chloromethane undergoes a substitution reaction in which Cl- is replaced by OH-:
CH3Cl(aq)+OH-(aq) <--> CH3OH(aq) + Cl-(aq)
The equilibrium constant Kc is 1*10^16.
Calculate the equilibrium concentrations of CH3Cl, CH3OH , OH- and Cl- in a solution prepared by mixing equal volumes of 0.1 M CH3Cl and 0.6 M NaOH . (Hint: In defining x, assume that the reaction goes 100% to completion, and then take account of a small amount of the reverse reaction.)
