PLEASE INCLUDE ANY CODE NECESSARY. The oxidation of carbon monoxide, in the presence of water vapour, is described by the following irreversible reaction:
CO(g)+12O2(g)CO2(g)
The rate law for this reaction is
-rCO=1.261010exp(-20131T)CCOCO20.25CH2O0.5
where T is in K , the concentrations are in molm3, and rCO is in molm3*s.
The reaction occurs in a CVBR (constant volume batch reactor) with the following composition at time t=0 :
COat2mol%,O2at1mol%,H2Oat7mol%, and N2at90mol%
All components, including the product CO2, behave as ideal gases. (Note that water vapour and nitrogen gas do not appear in the overall reaction.)
Initialy, at t=0, the P,T, and V of the CVBR are: 1bar,700K, and 0.2m3.
The CVBR is not adiabatic; it is exposed to external heat transfer given by
q=UHTA(T-T)
where UHT is the overall heat transfer coefficient, A is the area over which heat transfer occurs, T is the temperature inside the reactor, and T is some constant temperature (usually that of a temperature bath).
This heat transfer mechanism is an attempt to regulate the reactor temperature at 700 K (although you will show that it is not perfect). Suppose a heat exchanger is installed with
UHT=2Wm2*K;,A=1.5m2;,T=700K
(a) Show plots of T vs t and xCO vs t for a reaction with heat transfer as described. What is the conversion of CO at t=10min ?
Your time (horizontal) axes should be from 0 to 600 s (10 min ). The temperature axis should begin at 700 K .
(b) What is the maximum temperature experienced by the reactor? At what time (to within +-1s does this maximum temperature occur?
Note: Since this problem involves the same reaction as in the class problem on July 08, to save you some time, the enthalpy of reaction (as shown in class) is
rH(T)=-2.7959105-18.61T
+(2.522410-2)T2-(1.224710-5)T3+(2.25510-9)T4 all SI units
