If the equilibrium constant of the reaction 2 HI leftharpoons H_ 2...

If the equilibrium constant of the reaction 2HI⇌H2+2 \mathrm{HI} \rightleftharpoons \mathrm{H}_{2}+\mathrm{I}2_{2} is 0.25,0.25, then the equilibrium constant for the reaction H2+\mathrm{H}_{2}+\mathrm{I}2⇌2HI_{2} \rightleftharpoons 2 \mathrm{HI} would be

Options

  1. A1
  2. B2
  3. C3
  4. D4

Correct answer

D. 4

Step-by-step solution

When the reaction is reversed, \mathrm{K}^{\prime}=1 K=10.25=\frac{1}{\mathrm{~K}}=\frac{1}{0.25}=4
