Writing Expressions for K p. When one or more of the species in a system exists in the gaseous phase, the partial pressure of that species can be used in the equilibrium expression Dissolved species are still expressed as moles per liter (molarity). Top. Examples. Examples of equilibrium expressions K c for a
At equilibrium in question 1, the concentration of each is 3x and 2x respectively, because in a 1 molar solution of Ca3(PO4)2, you have 3 moles of Ca and 2 moles of PO4. In the second question, a 1 molar solution of CaCl2 in a 0.01 molar solution of NaCl contains 1 mole of Ca and (0.01 moles plus 2 moles) of Cl.
