What is Keq for the reaction N2 + 3H2 2NH3 if the equilibrium concentrations are [NH3] = 3 M, [N2] = 1 M, and [H2] = 2 M?
Licemer1 [7]

Answer : The correct option is, (D) k_{eq}=1.125

Explanation : Given,

Concentration of NH_3 = 3 M

Concentration of N_2 = 1 M

Concentration of H_2 = 2 M

The given balanced equilibrium reaction is,

N_2(g)+3H_2(g)\rightleftharpoons 2NH_3(g)

The expression for equilibrium constant for this reaction will be,

K_{eq}=\frac{[NH_3]^2}{[N_2][H_2]^3}

Now put all the given values in this expression, we get the value of K_{eq}

K_{eq}=\frac{(3)^2}{(1)\times (2)^3}

K_{eq}=1.125

Therefore, the value of K_{eq} for the given reaction is, 1.125

The atoms on the products side are bonded into different molecules from the atoms on the reactants side is the chemical changes occured.

<u>Explanation:</u>

  • The reaction commences when the compounds on the reactant side are ready to react to give the product.  
  • The reaction initiated by the transfer of electrons and molecules from the reactants to give the combined product of both the reactants.  
  • It is a process on which there will be rearrangement in the structure of molecules of a substance from its physical for more chemical form.  
  • In the above picture it shown that the red molecules combined with the white molecules additionally and changed the structure.
