Answer:
The equilibrium constant for CO now
= 0.212 M
For H₂O
= 0.212 M
For CO₂ = x = 0.2880 M
For H₂ = x = 0.2880 M
Explanation:
The chemical equation for the reaction is:
CO(g) + H2O(g) ⇌ CO2(g) + H2(g)
The ICE Table for this reaction can be represented as follows:
CO(g) + H2O(g) ⇌ CO2(g) + H2(g)
Initial 0.5 0.5 - -
Change -x -x + x + x
Equilibrium 0.5 -x 0.5 - x
The equilibrium constant![K_c = \dfrac{[x][x]}{[0.5-x][0.5-x]}](https://tex.z-dn.net/?f=K_c%20%3D%20%5Cdfrac%7B%5Bx%5D%5Bx%5D%7D%7B%5B0.5-x%5D%5B0.5-x%5D%7D)
![K_c = \dfrac{[x]^2}{[0.5-x]^2}](https://tex.z-dn.net/?f=K_c%20%3D%20%5Cdfrac%7B%5Bx%5D%5E2%7D%7B%5B0.5-x%5D%5E2%7D)
where; 
1.3583 (0.5-x) = x
0.67915 - 1.3583x = x
0.67915 = x + 1.3583x
0.67915 = 2.3583x
x = 0.67915/2.3583
x = 0.2880
The equilibrium constant for CO now = 0.5 - x
= 0.5 - 0.2880
= 0.212 M
For H₂O = 0.5 - x
= 0.5 - 0.2880
= 0.212 M
For CO₂ = x = 0.2880 M
For H₂ = x = 0.2880 M
In chemistry, there is a common note that says, "Like dissolves like".
This pertains to the concept that polar substances can dissolve only other polar substances. Also, nonpolar substances are also only able to dissolve nonpolar substances.
Polarity of the substance depends primarily on the type of bond and the difference in electronegativity.
Water is a polar substance while vegetable oil is not. From the concept presented above, it may be concluded that water will not be able to dissolve the vegetable oil and the assumption is logical.
The answer to your question is Hubble’s law
Answer:
<u>Reaction is called exergonic when ΔG is negative i.e. ΔG < 0</u>
Explanation:
The Gibbs free energy represents the spontaneity or feasibility of a given chemical reaction at constant pressure and temperature and is given by the equation:
ΔG = ΔH - TΔS
Here, ΔG - change in the Gibbs free energy
ΔS - change in the entropy
ΔH - change in the enthalpy
T - temperature
If the value of <u>ΔG for a chemical reaction is positive i.e. ΔG > 0</u>, then the given chemical reaction is said to be nonspontaneous. Such a reaction is called endergonic.
Whereas, if the <u>ΔG value for a chemical reaction is negative i.e. ΔG < 0</u>, then the given chemical reaction is said to be spontaneous. Such a reaction is called exergonic.
Explanation:
Since, aluminium chloride is an eye and skin irritant. Therefore, it is better to follow safety measures while dealing with such a chemical.
Hence, it is good to wear a lab coat while working in a laboratory and wear chemical resistant gloves so that our skin does not come in contact with the chemical.
Also, safety glasses will prevent the eyes if there is spurting of chemical.
Thus, we can conclude that chemical-resistant gloves, a lab coat, and safety glasses will prevent you from coming into contact with the given hazard.
