The ratio of concentration of product to the concentration of reactant is represented as equilibrium constant. The equilibrium constant is expressed as.
Base dissociation constant represents the strength of a base in a solution. The strength of the base is represented by the equilibrium constant expression.
The expression forcan be written and calculated as follows:
Example:
Then
ICE-table is the method of expressing the concentration of species which under go equilibrium.
ICE table can be written as
Since equilibrium constant was given
Then on rearranging the above equation
Ans:
