Questions asked by users might not always be phrased in the clearest way.

Determine the equilibrium constant for the following reaction if [hi] = 0.85 m, [h2 ] = 0.72 m and [i2 ] = 1.5 Mrnrn 2 hi h2 + i2

Accepted Answer

The equilibrium constant (Kc) for the reaction 2 HI ⇌ H2 + I2 can be calculated using the following equation:
Kc = ([H2][I2]) / [HI]^2
Substituting the given equilibrium concentrations:
Kc = (0.72 M
1.5 M) / (0.85 M)^2
Kc ≈ 1.49
