CVBR1. The gas phase reaction (p187)
was carried out in a constant-volume batch reactor where the following concentrations measurements were recorded as a function of time.T, min0591522304060
CA, mol/dm-321.61.351.10.870.700.530.35
Determine the order and rate of reaction.2. The following data were reported for a gas-phase constant-volume decomposition of dimethyl ether at 504C in a batch reactor. Assuming that the reaction goes to completion, determine the reaction order and specific reaction rate.3. From the previous problem, why is it that the total pressure measurement at t=0 is missing? Can you estimate it?4. The gas phase decomposition is carried out in a constant-volume batch reactor. Runs 1 through 5 were carried out in 100C, while run 6 was carried out at 110C. Determine the reaction order and specific reaction rate.RUNCA0, gmol/Lt1/2, min

5. N2O5 decomposes into NO2 and NO3 with a rate constant of 1.96 x 1014 exp[-10,660/T]s-1. At t = 0, pure N2O5 is admitted into a constant temperature and volume reactor with an initial pressure of 2 atm. After 1 min, what is the total pressure of the reactor? T = 273KVVBR1. A gas containing 40% each of A and B and 20% inerts undergoes the reaction: with rate equation: . The charge is 100 gmol and the temperature stays at 500C. It is required to find the time when the content B becomes 11.8% when the pressure is constant at 10 atm.
