The value of Keq for the following reaction is 0.25: SO2 (g) + NO2 (g) É SO3 (g) + NO (g) What is the value of Keq at the same temperature for the reaction below ? 2SO2 (g) + 2NO2 (g) É 2SO3 (g) + 2NO (g)

0.0625

Explanation:

The expression of the first reaction;

SO2 (g) + NO2 (g) --> SO3 (g) + NO (g)

Keq = [SO3] [NO] / ([SO2] [NO2])

The expression of the second reaction;

2SO2 (g) + 2NO2 (g) --> 2SO3 (g) + 2NO (g)

Keq = [SO3]² [NO]² / ([SO2]² [NO2]²)

Keq (Second) = Keq(first)²

Keq (Second) = 0.25² = 0.0625

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
