QUESTIONS A mixture of 28% SO2 and 72% air is charged to a flow reactor in which SO 2 is oxidized in the presence of N2 as follows: 2502 + O2 2503 If the reaction is carried out isothermally and neglecting pressure drop, evaluate the species concentrations as a function of conversion for the case when the total pressure is 1485 kPa and the temperature is constant at 227C and determine the concentration of SO2 and SO3 for X-0.25 and X = 0.75
