What is the density of kcl at 25.00 °c if the edge length of its fcc unit cell is 628 pm?

The relationship between the equilibrium constant of reaction and the rate constants for the forward and reverse reactions in a single step reaction is

Explanation:

Equilibrium constant is the ratio of product of the concentration of products to the product of concentration of reactants.

For example if the reaction is :

Rate of forward direction=

Rate of backward direction=

At equilibrium, Rate of forward direction = Rate of backward direction

thus

where

Thus
