When the rate of the forward reaction is equal to the rate of the backward reaction,the state is known as.......

For the reaction $2HI_{(g)} \rightleftharpoons H_{2(g)} + I_{2(g)}$,the equilibrium constant $K$ at room temperature is $2.85$,and at $698 \ K$ it is $1.4 \times 10^{-2}$. This indicates that:

Which of the following nitrogen oxides is the most stable?

Explain solid-vapour equilibrium by example.

Which of the following statements is correct regarding the equilibrium constant $(K)$?

The $K_c$ for $H_{2(g)} + I_{2(g)} \rightleftharpoons 2HI_{(g)}$ is $64$. If the volume of the container is reduced to one-half of its original volume,the value of the equilibrium constant will be
