1. The irreversible, gas-phase reaction A ------------ 2B+C is being carried out in an adiabatic, plug-flow reactor. Pressure drop in the reactor can be neglected. The feed to the reactor consists of A and H20 in a 1/1 molar ratio. No other species are present in the feed. Water is an inert diluent; it is not a reactant or a product. The ideal gas laws are valid. Write an expression for the concentration of A (CA) at any point in the reactor as a function of the fractional conversion of A (Xa). This expression may include the inlet temperature (To) and the adiabatic temperature change (deltaTad)· However, it may not include any other temperature.
