Which is the correct expression for Keq when the chemical reaction is as follows:
N2 + 3H2 2NH3.

The expression of the Keq is [NH3]2/([N2][H2]3). The common formula of reaction: ax+by=cz is Keq - [z]c/([x]a*[y]b). Remember to use a balanced chemical reaction.

Answer : The expression for equilibrium constant will be,

[tex]K_{eq}=\fac{[NH_3]^2}{[N_2][H_2]^3}[/tex]

Explanation :

Equilibrium constant : It is defined as the number of ratio of the concentration between the products and the reactants at equilibrium.

The equilibrium reaction is,

[tex]aX+bY\rightleftharpoons cW+dZ[/tex]

The general expression for equilibrium constant will be,

[tex]K_{eq}=\frac{[X]^a[Y]^b}{[W]^c[Z]^d}[/tex]

The given balanced chemical reaction will be,

[tex]N_2+3H_2\rightleftharpoons 2NH_3[/tex]

The expression for equilibrium constant will be,

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