Answer:

See below.

Explanation:

I'll do the second row for you the other 2 are done in exactly te same way.

B. Area of 1 side of cube = 2*2 = 4.

Surface area = 4*6 = 24

Volume = 2*2*2 = 8.

Surface area / volume = 24/8 = 3.

Ratio of Suface Area to Volume = 24 : 8 = 3 : 1. (divide both by 8)

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
