The value of Kc for the reaction (formation of ammonia by haber process) is 0.50 at 400º C.What will be the value of Kp at 400ºC when concentration are expressed in mole litre.1 and pressure in atmosphere ?

SOLUTION: 

For the reaction N2(g) + 3H2(g) ⇌ 2NH3(g) The Kp is 4.3 × 10^-4 at 375°C. Calculate Kc for the reaction. ?

SOLUTION:

Methanol (CH3OH) is manufactured industrially by the reaction CO(g) + 2H2(g) ⇌ CH3OH(g) The equilibrium constant (Kc) for the reaction is 10.5 at 220°C. What is the value of Kp at this temperature ?

 SOLUTION: Give Data ,Kc = 10.5 ,T= 220oC = (220 + 273)K = 493 K

At 700 K, the equilibrium constant Kp, for the reaction, dissociation of Sulphur trioxide to Sulphur dioxide is 1.8 × 10^3 kPa What is the numerical value of Kc for this reaction at the same temperature

SOLUTION:
