Q3. The elementary irreversible gas phase reaction A(g) + B(g) → C (g,l) is carried out isothermally in a PFR in which there is no pressure drop. The feed is equal molar in A and B, and there are no inerts or other species entering the reactor and the total pressure at the entrance is 2 atm. The initial concentration CA0 = 0.02 mol/dm and the reaction constant k = 100 dm/(mol.min).

Transcribed Image Text:Q3. The elementary irreversible gas phase reaction
A(g) + B(g) → C (g,l)
is carried out isothermally in a PFR in which there is no pressure
drop. The feed is equal molar in A and B, and there are no inerts
or other species entering the reactor and the total pressure at the
entrance is 2 atm. The initial concentration CA0 = 0.02 mol/dm
and the reaction constant k, = 100 dm/(mol.min).
1. Construct a complete stoichiometric table for this
reaction.
2. Use the stoichiometric table to calculate the the pressure
of the reactants inside the reactor at different values of
conversion (X=0, 0.2, 0.4, 0.6, 0.8, 1). Draw the relation
between conversion and partial pressure.
3. As the reaction proceeds the partial pressure of product C
builds up and a point is reached at which C begins to
condense. The vapor pressure of C is 0.4 atm. What is
the conversion of reaction at the point at which C first
starts to condense.
