When the rate of the forward reaction becomes equal to the rate of the backward reaction,this state is termed as:

In which of the following reactions,the concentration of product is higher than the concentration of reactant at equilibrium? $(K = \text{equilibrium constant})$

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

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

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

Equilibrium is a steady state,but it is dynamic in nature. What is the meaning of this statement?
