Question

Which of the following occurs when a reaction in a solution is at equilibrium and more product is added to the solution?No change will occur Equilibrium shifts to produce more reactant Equilibrium shifts to produce more product The reaction will stop

Answer 1

Equilibrium shifts to produce more reactant

Step-by-step explanation:

• Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.

• When more product is added to the solution:

This will increase the concentration of the products side, so the reaction will be shifted to the lift side (reactants side) to suppress the increase in the concentration of Products.

So, the right choice is: Equilibrium shifts to produce more reactant
