The irreversible gas-phase reaction A + 2B 4C takes place in a batch reactor of a constant volume V. It is initially loaded just with A and B at concentrations of CA = 2.5 mol/L and CB = 4.5 mol/L, respectively. Is there a density change upon the reaction? Which is the limiting species of the reaction? Substantiate yourself with some mathematics. Present the stoichiometric table in terms of the initial and final concentrations of the limiting species. Do not yet plug any numbers in these expressions. You may also employ here V. If the limiting species finally achieves a fractional conversion of 0.86, determine the corresponding concentration of each species.
