A mixture of 0.10 mol of NO, 0.050 mol of H2, and 0.10 mol of H2O is placed in a 101 300 K. The following equilibrium is established 3. 2 NO (g) + 2 H2 (g) N2 (g) + 2 H2O (g) At equilibrium [NO] 0.062 M. (a) Calculate the equilibrium concentrations of H2, (b) Calculate Kc 4. At 2000 C the equilibrium constant for the reaction

Explanation / Answer

Ans 1 :

a) The reaction SO3 = SO2 + 1/2O2 , is reverse of the actual reaction.

So the kp is given as : 1 / 1.85

= 0.54

b) The reaction 2SO2 + O2 = 2SO3 , is exactly double of the original reaction.

So kp will be given as : (1.85)2

= 3.4225

c) kc = kp / (RT)n

where n is change in number of moles = -1

kc = 3.4225 / (0.0831 x 1000)-1

kc = 284.4
