Consider the following generic reaction. a 2 b ( g ) − ⇀ ↽ − 2 a ( g ) + b ( g ) the initial concentration of a 2 b is 0.87 m and the initial concentrations of a and b are assumed to be zero. what is the equilibrium constant expression ( k c ) , if the equilibrium concentration of b is represented by x ?

Answer : The equilibrium constant expression will be

Solution :

Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.

The given equilibrium reaction is,

Initially conc.     0.87          0           0

At equilibrium  (0.87-x)      2x          x

The expression of will be,

Therefore, the equilibrium constant expression will be

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
