At certain temperature and pressure, hydrogen molecules have an average velocity of 607 m/s. What is the average velocity of carbon dioxide molecules under the same conditions?

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .

i believe the answer is a.
