The formation of styrene from vinylacetylene is essentially irreversible and follows an elementary rate law:

2 vinylacetylene ? styrene

2A ? B

The following data is available: CA0 = 1 mol / dm3 ; FA0 = 5 mol/s ; ?HR = -231 - 0.12( T -298) kJ/mol CP,A = 0.1222 kJ/(mol K) ; k = 1.48 x 1011exp (-19,124/T) dm3 /(mol s) T0 = 675 K ; Ua = 5.0 (kJ/(s*dm3*K) ; Text = 700 K

a) Determine the conversion achieved in a 10-dm3 PFR for an entering temperature of 675 K. Plot the temperature and conversion down the length (volume) of the reactor.

b) Vary the entering temperature and plot the conversion as a function of entering temperature.
