Use the Debye-Huckel limiting law to obtain the mean ionic activity coefficient (γ±). What is the magnitude of the error in the calculated fraction dissociated if concentrations are employed in the calculation instead of activities?

The answer is celsius 

Answer is: the equilibrium  shifts toward the reactants, to the left side of chemical reaction.it is because lead(ii) nitrate dissociates in water: pb(no₃)₂ → pb²⁺(aq) + 2no₃⁻(aq).according to lechatelier's principle, the position of equilibrium moves to counteract thechange (more lead cations, common ion), the position of equilibrium will move so that the concentration ofproducts decrease and concentration of reactants of chemical reaction increase.read more on -
