a) set up a stoichiometric table for this reaction for a flow system.
b) write the rate law for the disappearance of ONCB, - rA solely as a function of conversion X
c) what is the rate of reaction, - rA when X=0.9 at
i 461K ii. 561K
d) what would be the CSTR reactor volume to achieve 90% conversion at 561K for a molar feed rate of 2mol/min.Calculate the space time for this reactor.
(use R=1.987cal/mol.K, where R is the universal gas constant)
