The following gas phase reaction is taking place in a plug flow reactor. A stoichiometric mixture of A and B at 300 K is fed to the reactor. At 1 m along the length of the reactor, the temperature is 360 K. The pressure drop is negligible and an ideal gas behaviour can be assumed. Identify the correct expression relating the concentration of A at the inlet (CA0), concentration of A at 1m (CA) and the corresponding conversion of A (X) ?

A. CA = 1.2 CA0 (1 – X)/(1 – 0.33X) B. CA = 1.2 CA0 (1 – X)/(1 – 0.5X) C. CA = 0.83 CA0 (1 – X)/(1 – 0.33X) D. CA = 0.83 CA0 (1 – X)/(1 – 0.5X)...
