What are the following equations for each: 1. Ratio of product concentrations reactant concentrations at equilibrium.

2. Ratio of partial pressures of products to partial pressures of reactants (for gas phase reactions only) at equilibrium

3. Ratio of products reactants for the reaction of a weak base with water at equilibrium.

4. The thermodynamic equilibrium constant, calculated from thermodynamic data, not concentrations.

5. The autoionization constant for water (= 1.0 x 10-14).

6. Ratio of products reactants for the reaction of a weak acid with water at equilibrium

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.

the product of the pressure and volume is also constant
