What is the value of the equilibrium constant at 25 oC for the reaction between the pair: Sn(s) and Pb2 (aq) to give Pb(s) and Sn2 (aq) Use the reduction potential values for Sn2 (aq) of -0.14 V and for Pb2 (aq) of -0.13 V Give your answer using E-notation with NO decimal places (e. g., 2 x 10-2 would be 2E-2; and 2.12 x 10-2 would also be 2E-2.). Do NOT include spaces, units, punctuation or anything else silly
