Question

(07.07 MC) Consider the following equilibrium reaction having gaseous reactants and products. 4HCl + O2 ⇌ 2H2O + Cl2 Which of the following would result from increasing the volume of hydrochloric acid? (4 points) Select one: a. The volume of oxygen increases. b. The volume of chlorine decreases. c. The volume of water vapor increases. d. The rate of backward reaction increases.

Answer 1

Answer: b. the volume of water vapour increases

Explanation:

when there's an increase in concentration, the equilibrium favours the forward reaction, more product is produced, froward reaction is faster
