lodine, 12 and bromine, Br2 react in a closed 2.0-L container at 150°C to produce iodine monobromide, Br, according to the following equation: 12 + Br2 → 2 Br The equilibrium constant, K, at this temperature is 1.2 x 10^2. What are the equilibrium concentrations of all entities in the mixture if the container initially contained 4.00 mol each of iodine and bromine?

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.
