Question

Pb(s)|PbSO4(s)|SO2−4(aq,0.60 M)||H+(aq,0.70 M)|H2(g,192.5 kPa)|Pt. If E◦for the cell is 0.36 V at 25◦C, write
the Nernst equation for the cell at this temperature.
out of the five following choices, which one is correct
1.E= 0.36 + 0.01285 ln 192.5(0.70)2(0.60)
2.E= 0.36−0.02569 ln 192.5(0.70)2(0.60)
3.E= 0.36−0.01285 ln1.90(0.70)2(0.60)
4.E= 0.36 + 0.01285 ln 1.9(0.70)2(0.60)
5.E= 0.36−0.01285 ln 1.90(0.70)(0.60)

Answer 1

I don't agree with any of the answers. Look closely at the answers page from which you typed these. At least one answer should have a /0.60 in it. The 1.90 comes from 192.4/101.325 = 1.90
atm. Therefore, 3,4,or 5 should have the 0.60 in the denominator.
