When two reactants $A$ and $B$ are mixed to form products $C$ and $D$,what is the value of the reaction quotient $Q$ at the initial state of the reaction?

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

If the concentration of reactants is increased by $x$,then the equilibrium constant $K$ becomes:

Which statement for the equilibrium constant is true for the reaction $A + B \rightleftharpoons C$?

Given the reactions at $500 \ K$:
$(i) \ H_{2(g)} + 1/2 O_{2(g)} \rightleftharpoons H_2O_{(g)}$,$K_c = 2.4 \times 10^{47}$
$(ii) \ H_2O_{(g)} \rightleftharpoons H_{2(g)} + 1/2 O_{2(g)}$,$K_c = 4.1 \times 10^{-48}$
What does the magnitude of $K_c$ indicate about the formation of the product in reaction $(i)$?

Chemical equilibrium is dynamic in nature because
