applications of equilibrium

Question 1

what is the significance of the reaction quotient (q)?

Answer 1

the reaction quotient (q) is used to determine the direction in which a reaction will proceed to reach equilibrium. If q < k, the reaction proceeds to the right; if q > k, the reaction proceeds to the left.

Question 2

describe how the haber process utilises principles of chemical equilibrium.

Answer 2

• the haber process synthesises ammonia from nitrogen and hydrogen.
• by manipulating pressure, temperature, and using a catalyst, the equilibrium is shifted to favour the production of ammonia, despite being an exothermic reaction.
