2)What is the steady state approximation?

1)For the reaction A products, the temperature is increased from 300°C to 500°C, and then the times of reaction have been doubled What is the activation energy for the particular reaction? (se Arthenius theory)

Define selectivity and yield.?

Derive an performance equation for recycle reactor along with graphical representation.

The reactant A reacts according to second order kinetics 95% conversion of A is achieved in a single flow reactor. We buy a second reactor identical to the first. For the same 95% conversion, by how much he capacity is increased if we operate these two reactors in series. Do it for both mixed and plug flow reactors in series

At 650°C phosphene vapor decomposes as follows:

APH3 → P4 + 6H₂ -rph (10h-¹)Cph,What size of plug flow reactor operating at 650°C and 11.4atm.is needed for conversion of 10 mole/hr of phosphine in a feed of 75% is phosphane and rest is inert

One liter per minute of liquid containing A and B (CAo=0.10 mole/liter, CBo= 0.01mole/liter) flow into a mixed flow reactor of volume V-1 liter. The materials react in a complex manner for which the stoichiometry is unknown. The outlet stream from the reactor contains A, B and C (CA 0.02 mole liter, Cu 0.03 mole liter, Cer=0.04 mole/liter). Find the rate of reaction of A, B and C (ie, rA,rB,rC and to) for the conditions within the reactor

Discuss best arrangement of a set of ideal reactors (small mixed flow reactor, large mixed flow reactor and plug flow reactor) connected in series for any nth order reaction,n>0.

"An infinite equal size mixed flow reactors connected in series will give same performance as a single plug flow reactor" Justify.

Write difference between mixed and plug flow reactors.
