MCQ
In the reaction ${N_2}_{(g)} + 3{H_2}$ $\rightleftharpoons$ $2N{H_3}_{(g)}$, the value of the equilibrium constant depends on
  • A
    Volume of the reaction vessel
  • B
    Total pressure of the system
  • C
    The initial concentration of nitrogen and hydrogen
  • The temperature

Answer

Correct option: D.
The temperature
d
Arrhenius equation-

$k=Ae^{\frac{E_a}{RT}}$

where,

$k =$ rate constant of a chemical reaction

$E _{ a }=$ Activation energy.

$R =$ Universal gas constant

$A=$ Pre-exponential factor

From this, we can easily infer that the value of the equilibrium constant depends only on the temperature.
