space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

> 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.

answerto predict;

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )
