For a reversible reaction,if the concentration of reactants is increased,the equilibrium constant of the reaction

For the equilibrium $A \rightleftharpoons B$,the variation of the rate of the forward $(a)$ and reverse $(b)$ reaction with time is given by:

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

Chemical equilibrium is dynamic in nature because

The equilibrium constant in a reversible reaction at a given temperature:
