Question

One mole of nitrogen is mixed with three moles of hydrogen in a four litre container. If 0.25 percent of nitrogen is converted to ammonia by the following reaction

N₂(g) + 3H₂(g) ⇋ 2NH₃(g), then

calculate the equilibrium constant, K_c in concentration units. What will be the value of K_c for the following equilibrium?

1/2N₂(g) + 3/2H₂(g) ⇋ NH₃(g).

Answer 1

As 0.25% of nitrogen is converted into 2 x 0.0025 moles of ammonia are formed
