Reaction Engineering Quiz 4-5E2-E1>0, what kind of reaction is it? - ANS-Exothermic
E2-E1<0, what kind of reaction is it? - ANS-Endothermic
What does an endothermic reaction do? - ANS-Takes heat
What is a isotherm reactor? - ANS-No heat changes, temperature stays the same
Mass change in a reactor - ANS-Flow reactor
No mass exchange in reactor - ANS-Batch reactor
Space time behavior has no change - ANS-Stationary
What is not a mechanical variable - ANS-Constant temperature
What is the magnitude of a unimolecular elementary reaction pre-exponential factor
value in S-1 units - ANS-10E13
With infinite recycle rate, the PFR behavior is the same as CSTR - ANS-True
The batch reactor's reaction rate can be directly measured - ANS-False
Real world flow reactor will be between the CSTR and PFR, because it wont have
mixing nor complete mixing - ANS-True
Semi-batch reactor - ANS-dni/dt =v(t)*Ci0(t) - 0 + (vi*r*V)
PFR - ANS-0 = Fi - （Fi + dFi) + (vi *r *Ac*dL)
CSTR - ANS-0 = Fi0-Fi+(vi*r*V)
Batch Reactor - ANS-dni/dt = 0-0+(vi*r*V)
In a CSTR if the prodcuts and reactant are diluted, we can say it have negligible volume
or density changes - ANS-True
