In the chemical reaction $A \rightleftharpoons B$,the system will be known to be in equilibrium when:

In the reversible reaction,a catalyst is the substance which:

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?

For the reaction $A + 2B \rightleftharpoons C + 3D$,if the concentration of $B$ is increased at a constant temperature,the amount of product increases. What happens to the equilibrium constant of the reaction?

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

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