Chapter 20, Problem 20.5

(choose chapter or problem)

For a spontaneous reaction \(\mathrm{A}(a q)+\mathrm{B}(a q) \longrightarrow \mathrm{A}^{-}(a q)+ \mathrm{B}^{+}(a q)\), answer the following questions:

(a) If you made a voltaic cell out of this reaction, what half reaction would be occurring at the cathode, and what half-reaction would be occurring at the anode?

(b) Which half-reaction from (a) is higher in potential energy?

(c) What is the sign of \(E_{\text {cell }}^{\circ}\)? [Section 20.3]
