) In combustion of CO in moist air, the following reaction mechanism describes the initial stages of reaction: CO + O2 CO2 + O O + H2O OH + OH OH + CO CO2 + H H + O2 OH + O (1) Assuming that O and H are in quasi-steady-state, derive an expression for [OH] as a function of time in terms of [CO] and [O2] and the rate coefficients for the above reactions. During the initial stages of reaction, assume that T constant and [CO] and [O2] constant and equal to the initial concentrations, which are [CO]0 and [O2]0. (2) Using this result, write an expression for d[CO2]/dt. Is the reaction explosive (i.e., does the rate of formation of products increase exponentially in time)
