Question

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

Answer 1

Based on Le Chatelier's principle, if the equilibrium of a system is disturbed by changing the temperature, pressure or concentration, then it will shift in a direction to undo the effect of the induced change.

The given equilibrium is:

A + B ↔ AB

Removal of the reactant A implies that the concentration of A has decreased, therefore the equilibrium will shift in a direction to produce more of A. Thus, it will shift to the left and the rate of the reverse or backward reaction will increase.

Answer 2

AnsweR

The equilibrium SHIFTS LEFT. Simultaneously, there’s an increase in the REVERSE reaction.

Explanation:

A + B ⇌ AB
