At a certain temperature, the equilibrium constant, Kc, for this reaction is 53.3.
H2(g) + I2 (g) ---> 2 HI (g)
Kc= 53.3
At this temperature, 0.600 mol of H2 and 0.600 mol of I 2 were placed in a 1.00-L container to react. What concentration of HI is present at equilibrium?
For the given reaction -
H2(g) + I2 (g) ---> 2 HI (g)
I(M) 0.6 0.6 0
C -x -x +2x
Eq (0.6-x) (0.6-x) 2x
Therefore -
Kc = 53.3 = (2x)2 / (0.6-x)2
By solving the above equation, the value of "x" is 0.470 M
Thus, at equilibrium, [HI] = 2(0.470 M) = 0.94 M
