Question : 21 of 90

Marks: +1, -0

The following reaction is performed at 298 K.
2NO(g)+O2(g)⇌2NO2(g)
The standard free energy of formation of NO(g) is 86.6 kJ/mol at 298 K. What is the standard free energy of formation of NO2(g) at 298 K? (KP=1.6×1012)

[Main 2015]

86600+R(298)ln(1.6×1012)
86600−
ln(1.6×1012)
R(298)
0.5[2×86,600−R(298)ln(1.6×1012)]
R(298)ln(1.6×1012)−86600
