Suppose this reaction is at equilibrium. The following changes (stresses) will shift the equilibrium toward the product side or toward the reactant side. Classify each of the changes according to which side of the reaction is expected to shift due to the applied change.

well in order to answer this question you have to provide more information < 3

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
