Question

For the following balanced redox reaction,
Pb²⁺(aq) + H₂S(g) → Pb(s) + S(s) + 2H⁺(aq)
What is the E°_cell? Is the forward direction of the redox reaction spontaneous or nonspontaneous?

Accepted Answer

E°_{cell} = -0.27 VNonspontaneous

Answer

E°_{cell} = 0.27 VNonspontaneous

Answer

E°_{cell} = -0.010 VNonspontaneous

Answer

E°_{cell} = 0.010 VSpontaneous
