(membrane reactor) the first order, reversible reaction a< --> b + 2c is taking place in the membrane reactor. pure a enters and b diffuses through the reactor. unfortunately, some of the reactant a also diffuses through the membrane.

a. plot and analyze the flow rates of a, b and c down the reactor, as well as the flow rates of a and b through the membrane.

b. compare the conversion profiles of a conventional pfr with those of a membrane reactor. what generalizations can you make?

c. would the conversion of a be greater or smaller if c were diffusing instead of b?

d. discuss qualitatively how your curves would change if the temperature were increased significantly or decreased significantly for an exothermic reaction. repeat for an endothermic reaction.

additional info:

k= 10min-1

kc=0.01mol2/dm6

kca=1min-1

kcb=40min-1

fa0=100mol/min

v0 = 100dm3/min

vreactor=20dm3

note that this problem only needs you to set up the system of equations, supporting equations, parameters and b. c's for ode or equivalent solver.

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
