> 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.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
