Answer:
k = 4,92x10⁻³
Explanation:
For the reaction:
AB₂C (g) ⇄ B₂(g) + AC(g)
The equilibrium constant, k is defined as:
![k = \frac{[B_{2}][AC]}{[AB_2C]}](https://tex.z-dn.net/?f=k%20%3D%20%5Cfrac%7B%5BB_%7B2%7D%5D%5BAC%5D%7D%7B%5BAB_2C%5D%7D)
<em>(1)</em>
Molar concentration of the species are:
[AB₂C]: 0,0840mol / 5L = <em>0,0168M</em>
[B₂]: 0,0350mol / 5L = <em>0,0070M</em>
[AC]: 0,0590mol / 5L = <em>0,0118M</em>
Replacing this values in (1):
![k = \frac{[0,0070][0,0118]}{[0,0168]}](https://tex.z-dn.net/?f=k%20%3D%20%5Cfrac%7B%5B0%2C0070%5D%5B0%2C0118%5D%7D%7B%5B0%2C0168%5D%7D)
<em>k = 4,92x10⁻³</em>

The trend will be such that the time taken for the cross to disappear will be increasing.
<h3>Rate of reactions</h3>
The rate of reactions is affected by the concentration of reactants. The more concentrated the reactants are, the more the rate of the reaction, and vice versa. This is based on the condition that all other factors are kept constant.
In the illustrated reaction, the volume of sodium thiosulfate decreases downward while the volume of water increases. This means that the sodium thiosulfate gets more diluted as we move downward.
Thus, the reaction rate will keep decreasing. In other words, more time would be needed for the cross to disappear as the concentration of sodium thiosulfate decreases.

Hybridization of atomic orbitals produces orbital shapes and spatial orientations that correlate to those predicted in VSEPR theory.
<h3>What is VSEPR theory ?</h3>
The number of electron pairs surrounding an individual molecule's core atoms can be used to forecast a molecule's shape using the chemical model known as the valence shell electron pair repulsion hypothesis. The two principal creators of the theory, Ronald Gillespie and Ronald Nyholm, gave it the additional moniker Gillespie-Nyholm theory.
- Hybrid orbital theory explains how these forms are created, while VSEPR theory predicts the shapes of molecules. VSEPR theory's central tenet is that electron pairs—both those in bonds and those that are alone repel one another. "Groups" refers to the electron pairs, both in bonds and lone pairs.
