A voltaic cell is created with one half-cell consisting of a copper electrode immersed in 1.0 M CuSO4 solution and the other half cell consisting of a lead electrode immersed in a 1.0 M Pb(NO3)2 solution. Each half-cell is maintained at 25o C. What is the cell potential, in volts?
My dilemma is that I'm unsure on how to find the actual limiting reactant, and what information I should use. There's too much given; but from my introspection, we only need 1-Octene and the Pt catalyst
