A decimolar solution potassium ferrocyanide is 50% dissociated at 300 K. The osmotic pressure of solution is (R = 8.314 J K$^{-1}$ mol$^{-1}$):
For the reaction: 2SO2 + O2 → 2SO3, the rate of disappearance of O2 is \( 2 \times 10^{-4} \, \text{mol L}^{-1} \text{s}^{-1} \). What is the rate of appearance of SO3?
