Question

Consider the following chemical equation in equilibrium.

H2SO4(aq) <---> 2H+ + SO42–

What will happen to the chemical equilibrium if HCl is added to the system?
The chemical equilibrium will shift to the right.
The chemical equilibrium will be lost permanently.
The chemical equilibrium will not be affected.
The chemical equilibrium will shift to the left.

Answer 1

(D)

Step-by-step explanation:

Answer 2

I'd say that it will shift to the left because HCl will provide additional H+ ions which are present on the right side of the equation. Higher concentration of reagents on the one side - chemical equilibrium moves to the opposite side (le chatelier's principle)
