<u>Answer:</u> The equilibrium constant for the reaction is 54.47

<u>Explanation:</u>

The equilibrium constant is defined as the ratio of the concentration of products to the concentration of reactants raised to the power of the stoichiometric coefficient of each. It is represented by the term K_{eq}

The given chemical equation follows:

H_2+I_2\rightleftharpoons 2HI

The expression for equilibrium constant will be:

K_{eq}=\frac{[HI]^2}{[H_2][I_2]}

We are given:

[HI]_{eq}=1.3544\times 10^{-2}M

[H_2]_{eq}=4.5647\times 10^{-3}M

[I_2]_{eq}=7.378\times 10^{-4}M

Putting values in above expression, we get:

K_{eq}=\frac{(1.3544\times 10^{-2})^2}{(4.5647\times 10^{-3})(7.378\times 10^{-4})}\\\\K_{eq}=54.47

Hence, the equilibrium constant for the reaction is 54.47

ANTONII [103]

Answer:

19.27

Explanation:

Some values are corrected from correct source.Thus,

Moles of SO₂ = 8.19x10⁻² moles

Moles of O₂ = 8.10x10⁻² moles

Volume = 1 L

Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}

Concentration of SO₂ = 8.19x10² M

Concentration of O₂ = 8.10x10 M

Considering the ICE table for the equilibrium as:

                    2SO₂ (g) +    O₂ (g)     ⇔          2SO₃ (g)

t = o              8.19x10⁻²      8.19x10⁻²

t = eq                -2x                  -x                      2x

--------------------------------------------- --------------------------

neq:    8.19x10⁻² -2x       8.19x10⁻² -x                      2x

Given:  

Equilibrium concentration of  O₂ = 5.98x10⁻² M  = 8.19x10⁻² -x

Thus, x = 0.0212 M

[SO₂] = 8.19x10⁻² - 2*0.0212 = 0.0395 M

[SO₃] = 2*0.0212 = 0.0424 M

The expression for the equilibrium constant is:

K_c=\frac {[SO_3]^2}{[SO_2]^2[O_2]}  

K_c=\frac{{0.0424}^2}{{0.0395}^2\times 0.0598}  

K = 19.27

What is an ionic solution and how does it work in a battery?
frutty [35]

Explanation:

An ionic solution is a solution that has anions and cations. This is formed when ionic compounds dissociate in water. The ionic solution can be used as a battery because their respective ions can be attracted to either node of a battery. The cathode (+) attracts anions (negatively charged ions) and the anode (-) attracted cations (positively-charged ions). The reaction between the nodes and the respective ions in the solution causes electrons do be either donated or received. This ensures that the ionic solution (electrolyte) acts as channels for transport of electrons across the nodes to complete a circuit.
