The irreversible elementary reaction 2a > b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
(a) determine the concentration of a at the entrance to the reactor.
(b) if ca0 = 1.0 mol/l, what is the concentration of a at 90% conversion of a?
