Question

4HCI + O2 =2H20 + Cl2
Which of the following would result from increasing the concentration of H20?
The rate of the backward reaction increases.
The volume of hydrochloric acid decreases. Im
The rate of forward reaction increases.
The volume of chlorine increases.

Answer 1

The rate of the backward reaction increases

Explanation:

It is evident that if the reaction is left to proceed spontaneously, the forward reaction is favored because it results in a decrease in pressure in the system (The total reactants have 5 moles and the products have 3 in total).

Increasing H₂O concentration is then reaction, therefore, stymies the forward reaction and favors the reserves reaction. This is because the reverse reaction will lead to reduced pressure.
