The bond dissociation energy of H2 is 435 kJ/mol. The bond dissociation energy of a typical carbon-carbon single covalent bond is 347 kJ/mol. What can be concluded from this information

> 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 is b that is the answer.
