calculate

(a) the standard enthalpy, (

b) the standard Gibbs energy, of the reaction

4NO2(g) + O2(g) → 2N2O5(g)

Expert Solution

Solution :-

4NO2(g) + O2(g) → 2N2O5(g)

Formula to calculate the standard enthalpy change of the reaction is

Delta H rxn = sum of delta H product – sum of delta H reactant

= [N2O5*2] –[ (NO2*4)+(O2*1)]

= [11*2]-[(33.2*4)+(0*1)]

= -110.8 kJ

Now lets calculate the free energy of the reaction

Delta Grxn = sum of delta G product – sum of delta G reactant

= [N2O5*2] –[ (NO2*4)+(O2*1)]

= [118*2]-[(51*4)+(0*1)]

= 32 kJ

How can standard enthalpy and gibbs free energy of a reaction be used to determine yield...

How can standard enthalpy and gibbs free energy of a reaction be used to determine yield at a particular temperature and pressure? The standard enthalpy of formation at 298K is -45.4 kJ/mol and the standard gibbs free energy at 298K is -7.7kJ/mol. The problem requires that the yield of the reaction be determined at 325K and 50 atm. Any help with this would be greatly appreciated.
