Answer:
![Ka=\frac{[H^+][NO_2^-]}{[HNO_2]}](https://tex.z-dn.net/?f=Ka%3D%5Cfrac%7B%5BH%5E%2B%5D%5BNO_2%5E-%5D%7D%7B%5BHNO_2%5D%7D)
Explanation:
The reaction
The reaction of nitrous acid with water is a dissociation reaction of an acid:
The Ka equation
CAESIUM is the most reactive metal............
Answer: Equilibrium
Explanation:
The reactions which do not go on completion and in which the reactant forms product and the products goes back to the reactants simultaneously are known as equilibrium reactions.
For a chemical equilibrium reaction, equilibrium state is achieved when the rate of forward reaction becomes equals to rate of the backward reaction which means the products are being made as quickly as reactants
Equilibrium state is the state when reactants and products are present but the concentrations does not change with time.
