Answer:
The correct answer is A. See the explanation below
Explanation:
The equilibrium constant of a reaction is calculated as the ratio between the products (numerator) on the reagents (denominator) each raised by their stoichiometric coefficients.
The reaction
2S03 (reagents) -->2SO2 + 02 (products)
Keq= (products)/ (reagents) = (S02)^2 x (O2) /(S03)^2
