What is the value of P?(a) 3.6 mole/hr(b) 5.4 mole/hr(c) 6.4 mole/hr(d) 7.8 mole/hrI have been asked this question in class test.My question is taken from Recycle with Chemical Reaction in division Recycle, Bypass, Purge, Ideal Gases and Real Gases of Basic Chemical Engineering

Answer»

The correct ANSWER is (C) 6.4 mole/hr

Easy explanation: The extent of reaction = (4*0.9)/1 = 3.6, => moles of C2H6 = 3.6, moles of H2 = 6 – 3.6 = 2.4, moles of C2H4 = 4 – 3.6 = 0.4, => P = 3.6 + 2.4 + 0.4 = 6.4 moles/hr.
