The gas phase reaction A + 2B R is irreversible and is to be conducted in either a plug flow reactor or a mixed flow reactor under isobaric, isothermal conditions. This problem sets up the concentration calculations only. The initial concentration of A is 0.02 mol/dm³, and the initial concentration of B is 0.05 mol/dm3, and the feed rate is to be vo = 2 dm³/s at feedpressure P0. The reaction is elementary, -rA = kCACB^2, with a rate constant of 6.2 dm6/(mol2-s).

a) Provide formulas for the concentrations of A, B, R in terms of inserting calculated values for all other variables so that the only variable is .
