Question

What happens to a reaction at equilibrium when a reactant is removed from the reaction system

Answer 1

the equilibrium system will shift to replace some of what was removed

Step-by-step explanation:

le châteleir’s principle

Answer 2

When a reactant is removed based on a reaction at equilibrium, the condition favors the backward reaction. This obeys the Le Chatelier's principle which states that any disturbance in the system shall be dealt in a way that the system counters that disturbance.
