WHICH OF THE FOLLOWING IS THE CORRECT STATEMENT ABOUT CSTR REACTOR?

There is no input and outputflow

It is not a steady state

There is accumulation

It is a steady state

DETERMINE IF THIS STATEMENT IS TRUE OR FALSE:

"The Rate of Reaction is defined as the change in concentration of a substance divided by the time interval during which this change is observed”.

TRUE

FALSE

Ethanol undergoes partial oxidation to make synthesis gas:

The reaction is conducted in an isothermal, isobaric PFR. The feed is 10 mol/min each of the reactant and an inert gas, I. The temperature is 300°C and 2 atm.

a) Demonstrate which chemical is the limitingreactant. Rewrite the stoichiometric equation in terms of the limiting reactantis necessary. ____________

a) Find the initial volumetric feed rate tothe reactor. (R = 0.0821 Latm/mol.K) ____________

Which of the following is the design formula for batch reactor?

The gas phase reaction Aà B is carried out in a CSTR and the entering molar flow rate of A is 0.8 mol/s. Using data in Table 2-1, calculate the volume required to achieve 90% conversion.

7.089

14.4

14.33

10.49

Which of the following is the relative rate of reaction equation?

What are the units of k for the rate law: Rate = k[A][B]2, when the concentration unit is mol/L?

s-1

s

L mol-1s-1

L2mol-2s-1

Assuming A is constant over this range, work out how much faster a reaction with an activation energy of 40 kJ mol-1 would be at 40°C than at 20°C, assuming the concentrations of everything are the same. R = 8.31 J K-1 mol-1 .

____________

Taking A as your basis of calculation, construct a complete stoichiometric table for the reaction that taking place in batch reactor. 3A + 3B -> 3C +3D
