$A$ reversible reaction $H_2 + Cl_2 \rightleftharpoons 2HCl$ is carried out in a $1 \ L$ flask. If the same reaction is carried out in a $2 \ L$ flask,the equilibrium constant will be

For a reaction $H_2 + I_2 \rightleftharpoons 2HI$ at $721 \ K$,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

The equilibrium constant for the reaction $N_{2(g)} + O_{2(g)} \rightleftharpoons 2 NO_{(g)}$ is $4 \times 10^{-4}$ at $2000 \ K$. In the presence of a catalyst, the equilibrium is attained $10$ times faster. Therefore, the equilibrium constant, in the presence of the catalyst at $2000 \ K$ is:

Explain the types of physical equilibrium with examples.

In the given reaction $N_2 + O_2 \rightleftharpoons 2NO$,equilibrium means that

When pure ammonia is placed in a vessel at constant temperature,at equilibrium:
