A sample containing 0.35 moles of argon gas at 13 ° C and 568 torr pressure is heated to 56 ° C and increased to 897 torr. Calculate the change in volume (L)? A) 5 B) -3 C) 4 D) 1 E) -

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.
