Nitrogen is a greenhouse gas At equilibrium the rate of the forward and reverse

Question

Nitrogen is a greenhouse gas At equilibrium the rate of the forward and reverse reactions are equal. For the chemical equilibrium A + 2B 2C, the value of the equilibrium constant, k, is 10. What is the value of the equilibrium constant for the reaction 4C 2A + 4B. A reaction X + 2Y 3Z is started with 1.0 M of Z and no moles of X or Y. Complete the following ICE table (Just enter values based on this information) At 1200 K value of K_p for the following reaction is 27. 2KCIO_3(s) 2KCI(s) + 3O_2(g) Use this information to calculate the partial pressure of O_2(g) (PO_2) at 1200 K.

Explanation / Answer

21) When, A + 2B <==> C .... Kc = 10

For, 4C <==> 2A + 4B ..... Kc = 1/(10)^4 = 1 x 10^-4

22) ICE chart

             X   + 2Y <===> 3Z

I            -         -               1.0

C         +x       +x              -3x

E           x        x              (1 - 3x)

23) When, Kp = 27,

Kp = 27 = [p(O2)]^3

So, p(O2) = 3
