Chapter 17, Problem 66QAP

Consider a voltaic cell in which the following reaction takes place in basic medium at 25°C.
${\text{2NO}}_3{}^{\text{-}}\left(aq\right)+3{\text{S}}^{2-}\left(aq\right)+4{\text{H}}_2\text{O}\to 3\text{S}\left(s\right)+2\text{NO}\left(g\right)+8{\text{OH}}^{-}\left(aq\right)$
(a) Calculate E°.
(b) Write the Nernst equation for the cell E.
(c) Calculate E under the following conditions: $P_{\text{NO}}=0.994\text{atm},\text{ph}=13.7,\left[{\text{S}}^{2-}\right]=0.154M,\left[{\text{NO}}_3{}^{\text{-}}\right]=0.472M,$ .
