write the equilibrium constant expression, Kc, for this reaction: NiS(s) > Ni^+2(aq) + S^-2(aq). given that Ksp=3.0×10^-10

Homework Answers

Answer #1

NiS (s) ---------------->   Ni+2 (aq) + S-2 (aq)

                                        S                 S

Ksp = [Ni+2][S-2]

Kc = [products] / [reactants]

equilibrium constant expression, Kc = [Ni+2][S-2]

here in reactants NiS is in solid form. so that is not considered in equilibrium constant expression
