Question

For the equilibrium, 2NOCl(g) 2NO(g) + Cl2(g) the value of the equilibrium constant, Kc is 3.75 × 10–6 at 1069 K. Calculate the Kp for the reaction at this temperature?

13.8g of N2O4 was placed in a 1L reaction vessel at 400K and allowed to attain equilibrium N2O4 (g) 2NO2 (g). The total pressure at equilbrium was found to be 9.15 bar. Calculate Kc, Kp and partial pressure at equilibrium.

What is Kc for the following equilibrium when the equilibrium concentration of each substance is: [SO2]= 0.60M, [O2] = 0.82M and [SO3] = 1.90M ? 2SO2(g) + O2(g) 2SO3(g)

At a certain temperature and total pressure of 105Pa, iodine vapour contains 40% by volume of I atoms I2 (g) 2I (g). Calculate Kp for the equilibrium.
