For the reaction $N_2 + 3H_2 \rightleftharpoons 2NH_3$,the value of $K_c$ does not depend on: $(a)$ Initial concentration of reactants $(b)$ Pressure $(c)$ Temperature $(d)$ Catalyst

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

In the chemical equilibrium of a reversible reaction,which of the following does not cause any change?

In a reversible reaction $A \overset{k_1}{\underset{k_2}{\longleftrightarrow}} B$,the initial concentrations of $A$ and $B$ are $a$ and $b$,and the equilibrium concentrations are $(a - x)$ and $(b + x)$ respectively. Express $x$ in terms of $k_1, k_2, a$,and $b$.

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

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