Problem 1. [0.7 pt] Consider the selective catalytic reaction (SCR) reactions operated in a PFR at 700C and 2 bar: 6NO2(g)+8NH37N2(g)+12H2O(g) The molar flow rate for NH3 and NO2 are 5mol/s and 1mol/s, respectively. a) [0.1 pt] Determine limiting species b) [0.1 pt] Calculate the initial concentration of the limiting reactant c) [0.1pt] calculate d) [0.1 pt] Develop expressions for CNO2,CNH3,CN2 and CH2O in terms of the conversion X of the limiting species. e) [0.1 pt] Assuming the rate law is first order in NO2 and first order in NH3, express the rate law in terms of conversion X. f) [0.2 pt] If the rate constant is 0.02L/(mols), calculate the volume of PFR necessary to achieve 80% conversion
