For the reaction $H_{2(g)} + I_{2(g)} \rightleftharpoons 2HI_{(g)}$,the equilibrium constant changes with:

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

When chemical equilibrium is established in a reaction...

Pure ammonia is placed in a vessel at a temperature where its dissociation constant $(\alpha)$ is appreciable. At equilibrium,

$A$ 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
