उत्तर

For the reaction \[\ce{H2 (g) + I2 (g) ⇌ 2HI (g)}\], the standard free energy is  ∆GΘ > 0. The equilibrium constant (K ) would be K < 1.

Explanation:

The given chemical reaction is \[\ce{H2 (g) + I2 (g) ⇌ 2HI (g)}\]

By, thermodynamical equation of equilibrium,

∆GΘ = – RT ln K > 0

⇒ – RT ln K > 0

Now, R > 0 and T > 0

⇒ − ln K > 0

⇒ K < 1
