The elementary gas reaction 4A + 2B →20 is carried out isothermally in a PFR with no pressure drop. The feed is equal molar in A and B and the entering concentration of A is 0.1 mol/dm³. a) Calculate the entering concentration (mol/ dm³) of B b) Calculate the concentration of A and C (mol/ dm³) at 25% conversion of A c) Calculate the concentration of B (mol/ dm³) at 25% conversion of A d) Calculate the concentration of B (mol/ dm³) at 100% conversion of A e) If at a particular conversion the rate of formation of C is 2 mol/min/dm3, what is the rate of formation of A at the same conversion? f) What happened if the reaction was performed in a batch reactor? Do the calculation again for part b to e.

Question
Transcribed Image Text:The elementary gas reaction
4A + 2B →20
is carried out isothermally in a PFR with no pressure drop. The feed is equal molar in A
and B and the entering concentration of A is 0.1 mol/dm³.
a) Calculate the entering concentration (mol/ dm³) of B
b) Calculate the concentration of A and C (mol/ dm³) at 25% conversion of A
c) Calculate the concentration of B (mol/ dm³) at 25% conversion of A
d) Calculate the concentration of B (mol/ dm³) at 100% conversion of A
e) If at a particular conversion the rate of formation of C is 2 mol/min/dm3, what is
the rate of formation of A at the same conversion?
f) What happened if the reaction was performed in a batch reactor? Do the
calculation again for part b to e.
