Save Answer
Consider the following reaction with vanadium and iron:
2 Fe2+ (aq) + √2+ (aq)
2 Fe3+ (aq) + V(s)
When this reaction reaches equilibrium, what will be the cell potential (V)?
Fe3+ + e → Fe2+
E = +0.77
V2+ + 2e → V
E = -0.49
(the answer should be entered with 3 DIGITS; do not enter units; give answer in normal notation--examples include 0.00 and 1.23 and 120. and -123
and 123. and 12.3)
