The standard reduction potential, e′°, of any redox pair is defined for the half-cell reaction: oxidizing agent + n electrons → reducing agent the e′° values for the nad+/nadh and pyruvate/lactate conjugate redox pairs are −0.32 v and −0.19 v, respectively. (a) which redox pair has the greater tendency to lose electrons? explain. (b) which pair is the stronger oxidizing agent? explain. (c) beginning with 1 m concentrations of each reactant and product at ph 7 and 25 °c, in which direction will the following reaction proceed? pyruvate + nadh + h+ \rightleftharpoons lactate + nad+d) what is the standard free energy change (? g’°) for the conversion of pyruvate to lactate? e) what is the equilibrium constant (k’eq) for this reaction?
