Is it possible for a balloon with an initial internal pressure equal to 250.0 kpa
to naturally expand to four times its initial volume when the temperature
remains constant and atmospheric pressure is 101.3 kpa?

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
