<u>Answer:</u> The expression for equilibrium constant is
<u>Explanation:</u>
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
For the general chemical equation:
The expression for is given as:
For the given chemical reaction:
The expression for is given as:
The concentration of solid is taken to be 0.
So, the expression for is given as:
Answer : The value of at this temperature is 66.7
Explanation : Given,
Pressure of at equilibrium = 0.348 atm
Pressure of at equilibrium = 0.441 atm
Pressure of at equilibrium = 10.24 atm
The balanced equilibrium reaction is,
The expression of equilibrium constant for the reaction will be:
Now put all the values in this expression, we get :
Therefore, the value of at this temperature is 66.7
