Question

UI: The dimethyl ether (DME) can be thermally decomposed in the gas phase. One student team performed this reaction and measured the increase in the pressure at constant voluume batch reactor. At 500°C and initial pressure of 312 mmHg, the following deta where obtained: t, sec 390 777 (5 marks) 1195 3155 Ptotal, mm Hg 408 4 88 562 779 931 Assuming that only DME was present initially and that the reaction is (CH3)20 CH:+H+CO Hint: test for the rate dependence on the reactant DME providing a graph as art of your answer. This require you to find the partial pressure of DME at each time from the total pressure, knowing that Ntotal = NDME +NCHA+NH2+Nco, also assuming ideal gas (a) Determine the rate equation for the decomposition (the order and the rate constant) (b) What reactor is suitable for such reaction? (c) Explain what steps you should do if you decide to use a packed bed reactor filled with catalyst for that reaction (d) What are the codes of ethics implemented in that decomposition reaction?
