Definitions [1]
Explain Reversible reaction.
- Reactions which do not go to completion and occur in both directions simultaneously are called reversible reactions.
- Reversible reactions proceed in both directions. The direction from reactants to products is the forward reaction, whereas the opposite reaction from products to reactants is called the reverse or backward reaction.
- A reversible reaction is denoted by drawing in between the reactants and product a double arrow, one pointing in the forward direction and other in the reverse direction (⇌). e.g.
a. \[\ce{H_{2(g)} + I_{2(g)} ⇌ 2HI_{(g)}}\]
b. \[\ce{CH3COOH_{(aq)} + H2O_{(l)} ⇌ CH3COO^{-}_{ (aq)} + H3O^{+}_{ (aq)}}\]
