Which of these scenarios involve a reaction that is at equilibrium
a reaction is producing more products than reactants.
b the reaction is only producing proucts.
c the reaction is producing more reactants than products.
d the reactive is producing reactants and products at an equal rate.

The answer is "The reaction is producing reactants and products at an equal rate"

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.
