Equilibrium

What species are omitted in the Kc expression

solids and liquids

What species are omitted in the Kp expression

everything but gases

How to calculate partial pressure

Mole fraction of the molecule * Pressure in system

What can change equilibrium constant

Temperature only, concentration and pressure cannot

If forward reaction is exothermic, what happens to Kc when temperature increases

Equilibrium yield decreases, so Kc decreases

Why does changing concentration not affect the equilibrium constant/position

When concentration is increased on one side, the equilibrium shifts again to its previous state as more of the other side is produced
