For the cell Pt(s) | VO2+(0.116 M), V3+(0.116 M), H+(1.57 M) || Sn2+(0.031 8 M), Sn4+(0.031 8

Question:

For the cell Pt(s) | VO2+(0.116 M), V3+(0.116 M), H+(1.57 M) || Sn2+(0.031 8 M), Sn4+(0.031 8 M) | Pt(s), E (not E ) = - 0.289 V. Write the net cell reaction and calculate its equilibrium constant. Do not use E values from Appendix H to answer this question.
