2. The experimental data for a batch reaction showing the rate of decomposition of NO2 with time are given in TABLE Q2. Based on the available data, determine the initial NO2 concentration, the kinetic model for the reaction and the reaction constant, k. Draw the required graph and validate the rate constant. State ALL assumptions and equations used. Additionally, it seems that the adiabatic operation of the reactor produces unacceptable fall in temperature. Suggest TWO (2) temperature controlling methods in the reactor system design for next experiments.
