At this temperature, 0.400 mol of H2 and 0.400 mol of I2 were placed in a 1.00-L container to react. What concentration of Hi is present at equilibrium? Number 3 Previous Check Answer Ned

Explanation / Answer

H2 (g)   +   I2 (g)   <--------------->   2 HI (g)

0.400       0.400                                  0

0.4 - x      0.4- x                                    2x

Kc = [HI]^2 / [H2][I2]

53.3 = (2x)^2 / (0.4 - x)^2

2x / 0.4 - x = 7.301

2x = 2.92 - 7.301 x

x = 0.314

concentration of HI = 0.628 M
