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?

E°_cell = -0.27 V
spontaneous

Answer

E°_cell = 0.27 V
nonspontaneous

Answer

E°_cell = -0.010 V
nonspontaneous

Answer

E°_cell = 0.010 V
spontaneous
