\[\ce{1/2 H2 (g) + 1/2 I2 (g) ⇌ HI (g)}\]

What would be the equilibrium constant \[\ce{K_c}\] for the reaction

\[\ce{2HI (g) ⇌ H2 (g) + I2 (g)}\]

उत्तर

0.04

Explanation:

If the equation is multiplied by 2, the equilibrium constant for the new equation is the square of \[\ce{K}\] it means we must do the square of 5 that is 25. Then and on reversing the reaction the value of the equilibrium constant is inversed means the value of K comes out to be 1/25 = 0.04.
