Determine the molar concentration of Ag+, CN-, HCN and OH- in 50.0mL of saturated AgCN solution with an ionic strength of 0.05 as well as a pH fixed at 9.00. Presume that the equations shown are the only equilibrium that occur in this system. Explain the equilibrium constants offer are concentration equilibrium constants.
AgCN(s) <--> Ag+(aq) + CN-(aq) Ksp= 2.20 x10-16
H2O(l)+ CN-(aq) <--> HCN(aq) + OH-(aq) Ksp = 1.60 x 10-5
A particular reaction has a ?Ho value of -155 kJ and ?So of -282 J/mol K at 298 K. Assuming that ?Ho and ?So hardly change with temperature, determine the temperature in K at which the spontaneity of this reaction changes.
