Define chemical equilibrium state.
Give the characteristics of reversible reaction.
How is dynamic equilibrium established?
Why at equilibrium state reaction does not stop?
Why is equilibrium state attainable from either way?
What is relationship between active mass and rate of reaction?
Derive equilibrium constant expression for the synthesis of ammonia from nitrogen and hydrogen.
Write the equilibrium constant expression for the following reactions:

\mathrm{i.}\quad \mathrm{H}_{2(\mathrm{g})} + \mathrm{I}_{2(\mathrm{g})}\rightleftharpoons 2\mathrm{HI}_{(\mathrm{g})}

\mathrm{ii.}\quad \mathrm{CO}_{(\mathrm{g})} + 3\mathrm{H}_{2(\mathrm{g})}\rightleftharpoons \mathrm{CH}_{4(\mathrm{g})} + \mathrm{H}_{2}\mathrm{O}_{(\mathrm{g})}

How direction of a reaction can be predicted?
How can you know that a reaction has achieved an equilibrium state?
What are the characteristics of a reaction that establishes equilibrium state at once?
If reaction quotient \(Q_{c}\) of a reaction is more than \(K_{c}\) , what will be the direction of the reaction?
An industry was established based upon a reversible reaction. It failed to achieve products on commercial level. Can you point out the basic reasons of its failure being a chemist?
