Consider the complete oxidation of n-butanol, whose balanced reaction is shown below, for which ?G o'= -619.4 kcal/mol at 25.0 oC. CH3CH2CH2CH2OH + 6 O2 ? 4 CO2 + 5 H2O (a) What is the value of n for this redox reaction? (b) Calculate ?Eo'at 25.0 oC. (c) Using the half reaction for the reduction of oxygen (O2 + 2H+ +2e- --> H2O2), write the half reaction for oxidation of n-butanol. (d) Calculate Eo' at 25.0 oC for the n-butanol half reaction in (c) above
