MCQ

In the given reaction ${N_2} + {O_2}$ $\rightleftharpoons$ $2NO$, equilibrium means that

A
Concentration of reactants is changing where as concentration of products is constant
✓
Concentration of all substances is constant
C
Concentration of reactants is constant where as concentration of products is changing
D
Concentration of all substances is changing

✓

Answer

Correct option: B.

Concentration of all substances is constant

b
$N _2+ O _2 \rightleftharpoons 2 NO$

Equilibrium is the point where concentration of all substances are constant, but reaction occurs in both direction to maintain constant concentration.
