Draw the Lewis structure for each of the following and THEN determine the electron-pair geometry of the atom indicated. Do not i
Hoochie [10]

Answer: The electron pair geometry is linear

Explanation:

Carbon in carbon disulphide is surrounded by four electron pairs which is ordinarily expected to lead to a tetrahedral electron pair geometry according to Valence shell electron pair repulsion theory (VSEPR). However, the observed shape is linear due to the fact that double bonds cause more repulsion than single bonds. The double bonds force the molecule into a linear arrangement as in Carbon IV oxide molecule. See image attached for structures.

On analysis, an equilibrium mixture for the reaction 2h2s(g) 2h2(g) + s2(g) was found to contain 1.0 mol h2s, 4.0 mol h2, and 0.
mario62 [17]

Kc = 3.2

The chemical equation is

2H2S ⇌ 2H2 + S2

The equilibrium constant expression is

<em>K</em>c ={[H2]^2[S2]}/[H2S]^2

1. Calculate the <em>equilibrium concentrations</em> of each component

[H2] = (4.0 mol)/(4.0 L) = 1.0 mol/L

[S2] = (0.80 mol)/(4.0 L) = 0.20 mol/L

[H2S] = (1.0 mol)/(4.0 L) = 0.25 mol/L

2. Calculate the value of the <em>equilibrium constant</em>

<em>K</em>c = (1.0^2 x 0.20)/0.25^2 = 3.2
