<u>Answer:</u> The value of
for the equation is 
<u>Explanation:</u>
The given chemical reaction is:

The chemical equation for which the equilibrium constant is to be calculated follows:

As, the equation is the result of the reverse of given reaction. So, the equilibrium constant for the equation will be the inverse of equilibrium constant for the given reaction.
The value of equilibrium constant for the equation is:

We are given:

Putting values in above equation, we get:

Hence, the value of
for the equation is
