A 2.5 L flask contains a mixture f nitrogen gas and oxygen gas at 25°C. The total pressure of the gaseous mixture is
95 atm, and the mixture is known to contain 0.040 mol N2.
Calculate the partial pressure of oxygen and the moles of oxygen present

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.
