Equilibrium constant for the reaction?
Given the thermodynamic data in the table below, calculate the equilibrium constant for the reaction:
2 SO2 (g) + O2 (g) 2 SO3 (g)
Substance deltaHf° (kJ/mol) delta° (J/mol · K)
SO2 (g) -297 249
O2 (g) 0 205
SO3 (g) -395 256

For the hypothetical chemical reaction
a A + b B c C + d D
the equilibrium constant is defined as :
KC = [C]^c [D]^d / [A]^a [B]^b
The notation [A] signifies the molar concentration of species A. An alternative expression for the equilibrium constant involves partial pressures.
KP = PC^c PD^d / PA^a PB^b
