2. During long-range atmospheric transport over distances on the order of 1000 km, SO₂ emitted from power plants is oxidized to sulfate (SO4) and both compounds undergo dry deposition to the surface. The conversion and removal processes can all be treated as first order, with the rate constant for conversion given as k12, and the rate constants for deposition given as kid and k2d for SO₂ and SO4, respectively. The reaction system is shown in the diagram below. Assume that the air parcel in which SO₂ to SO4 conversion occurs can be treated as a plug flow reactor with wind velocity u. SO₂ kıd K12 SO4²- k₂d (a) Write the mass balance equations (differential equations) for SO₂ and SO4². (b) Solve for the steady state concentrations of each as a function of distance and write expressions for each of these. (c) Determine the maximum SO4² concentration and the distance at which it occurs, given u = 15 km/h, kid = 0.025 h¹, k2d = 0.015 h¹ and k12 = 0.02 h¹, and that the initial SO42 concentration is negligible. Express the maximum as a ratio of SO42 to initial SO₂ concentration.

Question
During long-range atmospheric transport over distances on the order of 1000 km, SO₂ emitted from power plants is oxidized to sulfate (SO) and both compounds undergo dry deposition to the surface. The conversion and removal processes can all be treated as first order, with the rate constant for conversion given as k, and the rate constants for deposition given as kand ka for SO₂ and SO, respectively. The reaction system is shown in the diagram below. Assume that the air parcel in which SO₂ to SO, conversion occurs can be treated as a plug flow reactor with wind velocity
