Question

For a reaction, $H_2\left(g\right)+I_2\left(g\right)\rightleftharpoons 2HI\left(g\right)$ at $721K$, the vapour of equilibrium constant is $50$. If $0.5$ mol each of $H_2$ and $I_2$ is added to the system, the value of equilibrium constant will be

• A. $40$
• B. $60$
• C. $50$
• D. $30$

Answer 1

The correct option is C $50$

For a reaction, $H_2\left(g\right)+I_2\left(g\right)\rightleftharpoons 2HI\left(g\right)$ at $721K$, the value of equilibrium constant is $50$. If $0.5$ mol each of $H_2$ and $I_2$ is added to the system, the value of equilibrium constant will be $50$. The value of equilibrium constant does not depends on the concentrations ( or partial pressures) of reactants and products.
