The equilibrium-constant expression for a reaction written in one direction is the of the one for the reaction written for the reverse direction.

Explanation:

The equilibrium constant for an equilibrium reaction is the ratio of the equilibrium constant for the forward reaction, Kf, to the equilibrium constant for the reverse reaction, Kr:

When you write the reaction in the other reaction, the forward and the reverse reaction are exchanged:

As you see:

Thus, the equilibrium-constant expression for a reaction written in one direction is the    reciprocal___ of the one for the reaction written for the reverse direction.

indium, and thallium have three electrons i think

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
