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 H2O 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 (ATad). However, it may not include any other temperature
