Question

Time: 12 minutes, 51 seconds. uestion Completion Status A sample of solid NH4HS is placed in a closed vessel and allowed to equilibrate. Calculate the equilibrium partial pressure (atm) of ammonia assuming that some solid NH4HS remains. 0070 03.8 O 4.9 x 10 0.52 0.26 QUESTION 10 Consider the following reaction: 2 H20g)+2 S02(g)2 H2Sa)+3 02(g) A reaction mixture initially contains 2.8 M H20 and 2.6 M SO2. Determine the equilibrium concentration of H2S if Kg for the reaction at this temperature is 1.3 x 10-6, O 0.058 M 0.028 M 00.045 M 31 x 10-3 M 0.12 M ck Save and Submit to save and submit.

Explanation / Answer

NH4HS(s) -------> H2S(g) + NH3(g)

Kp   = PH2S *PNH3

0.075   = x*x

0.075 = x^2

x      = 0.27

But in this problem KP value not given please give me KP value

10.

        2H2O(g) + 2SO2(g) ----------------> 2H2S + 3O2

I        2.8            2.6                                    0          0

C       -2x          -2x                                     2x        3x

E     2.8-2x      2.6-2x                                2x          3x

      Kc = [H2S]^2[O2]^3/[H2O]^2[SO2]^2

     1.3*10^-6    = (2x)^2(3x)^3/(2.8-2x)^2(2.6-2x)^2

    1.3*10^-6*(2.8-2x)^2(2.6-2x)^2   = (2x)^2(3x)^3

      x = 0.056

[H2S]   = 2x   = 2*0.06 = 0.12M >>>>answer
