Question
Calculate the value of equilibrium constant for the reaction:
There is 10.0 mol of N2, 14·0 mol of O2 and 0·2 mol of NO2 present at equilibrium in a 3·0L vessel at 298K.What will be the effect of increased temperature on the equilibrium constant?
Solution
The reversible reaction is
The equilibrium constant Kc is given by
Putting the values in expression (1), we have,
It is an exothermic reaction. According to Le-Chatterlier's principle, an increase in temperature would shift the equilibrium to left and the value of Kc should decrease.
