germanium (Ge), potassium (K), selenium (Se)
selenium (Se), germanium (Ge), potassium (K)
potassium (K), germanium (Ge), selenium (Se)

The list of elements in order from most conductive to least conductive is; potassium (K), germanium (Ge), selenium (Se).

Conductivity is a property of metals. The more "metallic" an element is, the greater its conductivity.

The most metallic element in the list is Potassium hence it has the highest conductivity (1.4×107 S/m) followed by germanium which is a semiconductor (2000 S/m). Selenium has the least electrical conductivity.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
