Sulphur dioxide (\(SO_2\)) gas diffuses through a stagnant air film of thickness 2 mm at 1 bar and 30°C. The diffusion coefficient of \(SO_2\) in air is\(1×10^{−5} m^2s^{−1}\). The \(SO_2\) partial pressure at the opposite side of the film are 0.15 bar and 0.05 bar. The universal gas constant is \(8.314 J/mol^{-1}K^{-1}\) Assuming ideal gas behavior, the steady state flux of \(SO_2\) in mol \(m^2s^{−1}\) through air film is
