Question

Consider the reaction between CO and O2 (carbon monoxide post combustion) described by the elementary reactions below. The temperature of the reacting system is 1500 K. The initial concentrations are shown below. Plot the concentration of each species as a function of time. Species: species CO CO2 initial concentration 1000 ppm 0 3% 0 remainder 5 There are four species. Elementary reactions: 1. CO + O2 + CO2 + 0 2. O2 + M +0+0+M k1 = 3.1 X 10^exp(-37.6/RT) k2 = 5.1 X 10^5exp(-115.0/RT) k6 = 5.9 x 105exp(-4.1/RT) 3. CO + 0 + M → CO2 + M.
