For the reaction below, the equilibrium constant is Kc = 3.2×
10−10 at 25 °C.
Pb(s) + 2 Cr3+(aq) ⇌ Pb2+(aq) + 2 Cr2+(aq)
Excess Pb(s) is added to a solution for which the initial concentration of Cr3+(aq) is 2.0 mol L−1. What are the equilibrium concentrations of Pb2+ and Cr2+ ?
Enter values accurate to 2 significant figures. Do not include units.
[Pb2+]eq = (0%) mol L−1
[Cr2+]eq = (0%) mol L−1
