For the thermal decomposition of nitrous oxide, 2N2O(g)-->2N2(g)+O2(g) , values of the parameters in the Arrhenius equation are A=4.2x10^9 s^-1 and Ea=222 kj/mol. If a stream of N2O is passed through a tube 30mm in diameter and 15cm long at a flow rate of 0.75L/min, at what temperature should the tube be maintained to have a partial pressure of 1.0mm of O2 in the exit gas? Assume that the total pressure of the gas in the tube is 1.30atm.
