Solution

The correct option is D 393.3kJ mol1
Standard enthalpy and standard entropy change for the oxidation of NH3 at 298K are 382.64kJmol1 and 145.6Jmol1K1 respectively.
Standard Gibbs energy change for the same reaction at 298K is 393.3kJmol1
ΔG0=ΔH0TΔS0
ΔG0=382.64kJmol1(298K×(145.6Jmol1K1)×103kJ/J)
ΔG0=393.3kJmol1
