The equilibrium constant expression is the ratio of the concentrations of the products over the reactants. Notice how each concentration of product or reactant is raised to the power of its coefficient. For example, the concentration of D is raised to the power of 3 since it is 3D in the balanced reaction.

Answer:
10.304 kPa
Explanation:
n=mol nitrogen (N2) gas=2moles
Temperature=T=310 K
Volume=0.5 L=0.5 dm3
R=8.31 J K−1 mol−1
From Gerenal gas equation we know that
PV=nRT
P=nRT/V
Putting the values
P=(2*8.31*3100/(0.5)
P=10.304 kPa
or P=10304 Pa
