Question

How does the equilibrium change to counter the removal of A in this reaction? A + B ⇌ AB The equilibrium shifts left. Simultaneously, there's an increase in the reverse reaction.

Answer 1

The increase in the reverse reaction

Step-by-step explanation:

Based on the LeCh's principle, a change in the concentration of a species in the equilibrium will shift the concentrations of the other species in order to counteract the effect of this change.

For example, for the reaction:

A + B ⇌ AB

Remove A in this reaction will produce the increase in the reverse reaction in order to increase the concentration of A.
