<u>Answer:</u> The equilibrium constant for the overall reaction is
<u>Explanation:</u>
The given chemical equations follows:
<u>Equation 1:</u>
<u>Equation 2:</u> ( × 2)
The net equation follows:
The equilibrium constant for the net reaction will be the multiplication of two above equations.
If the equation is multiplied by a factor of '2', the equilibrium constant of the net reaction will be the square of the equilibrium constant of respective reaction.
The value of equilibrium constant for net reaction is:
Hence, the equilibrium constant for the overall reaction is
