Differentiate between reversible and irreversible reaction?

Aspect Reversible reaction Irreversible reaction Definition A reversible reaction occurs in both forward and reverse directions. An irreversible reaction occurs in one direction only. Equilibrium It achieves a state of dynamic equilibrium where the rate of the forward reaction equals the rate of the reverse reaction. No equilibrium is established in such reactions.   Completion … Read more

How does a catalyst affect a chemical equilibrium?

Role of Catalyst: A catalyst speeds up both the forward and reverse reactions equally. It lowers the activation energy for both reactions, allowing equilibrium to be reached more quickly. Effect on Equilibrium Position: A catalyst does not change the position of equilibrium or the value of the equilibrium constant (Kc). It only reduces the time … Read more
