Nitrous oxide decomposes to nitrogen and oxygen in a closed batch reactor at a temperature of 1163K. The initial N2O pressure in the reactor was 101.3kPa. Calculate after what time, the pressure in the reactor rises to 141.3kPa, if the decomposition reaction is of the second order, the gases behave ideally and the rate constant of the decomposition has the value kc=0.977dm3mol1s1 at the given temperature. Also determine the half-life of the reaction
