Question

Which of the changes listed below has no effect on the equilibrium for the following reversible reaction? PbI₂(s)  Pb2+(aq)+ 2 I-(aq)

Quizplus · Accepted Answer

Adding solid PbI₂ does not affect the equilibrium because it is already present as a solid in the reaction. It does not change the concentrations of any of the species in the reaction. The other options would lead to a shift in the equilibrium either to the left or right.
