Answer 2

Answer:

Explanation:

The equilibrium reactions in aqueous solution are :

(1)          

(2)          

The final equilibrium reaction is :

       

Now we have to calculate the value of  for the final reaction.

Now equation 1 is multiply by 2 and reverse the equation 2, we get the value of final equilibrium reaction and the expression of final equilibrium constant is:

Now put all the given values in this expression, we get :

Therefore, the value of  for the final reaction is, 184.09
