If the reaction producing KCl from its elements goes essentially to completion, it is likely that the reaction is thermodynamically favorable. This means that the reaction will proceed spontaneously and release energy as it occurs.

Thermodynamic favorability is determined by the change in the enthalpy (heat) and the change in the entropy (disorder) of the system. If the change in enthalpy is negative (exothermic) and the change in entropy is positive (increase in disorder), the reaction is likely to be thermodynamically favorable.

In general, reactions that are thermodynamically favorable are more likely to occur spontaneously and go to completion, while reactions that are thermodynamically unfavorable are less likely to occur spontaneously and may not go to completion. However, other factors, such as the presence of catalysts or the rate at which the reaction occurs, can also affect the likelihood of a reaction occurring.

The moles of [tex]O_{2}[/tex] present in an infant's lungs, if the infant takes a full breath of air is [tex]1.46*10^{-4}[/tex] moles

We can calculate the moles in the following way

We have been given the following data,

The infant takes a full breath of air

Full breath of air= volume of lungs of the infant= 17 mL= [tex]\frac{17}{1000}[/tex] L

Pressure inside lungs(P)= 101.3* [tex]10^{3}[/tex] Pa= 1 atm

Temperature(T)= Room temperature= 298 K

Volume of Oxygen(V)= 21% of total volume of lungs= 21% of 17 mL

= [tex]\frac{21*17}{100}[/tex] mL

= 3.57 mL

= [tex]\frac{3.57}{1000}[/tex] L

Now, let the number of moles of oxygen the infant breathes be n.

Since PV=nRT

Therefore, n= [tex]\frac{PV}{RT}[/tex]

We know that the value of R is 0.082 L atm/K mol

n = [tex]\frac{(1* 3.57)}{(0.082*298*1000)}[/tex] moles of oxygen

Answer:

At equilibrium, the partial pressure of a gas is equal to the product of its equilibrium constant and the partial pressure of the other gases it reacts with. In this case, the equilibrium constant is given as K=6.9×10−6 at 1000 K, and the partial pressure of SO2 and Cl2 are both 0.760 bar. Therefore, the partial pressure of SO2Cl2 at equilibrium is:

6.9×10−6 * 0.760 bar * 0.760 bar = 4.3×10−8 bar

So the partial pressure of SO2Cl2 at equilibrium is 4.3×10−8 bar.

There are so many types of chemical reaction reaction like combination reaction, double displacement reaction. To solve such this we must know the concept of equilibrium reaction. Therefore, the partial pressure of SO[tex]_2[/tex]Cl[tex]_2[/tex] at equilibrium is 4.3×10⁻⁸bar.

Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved.

The balanced equation can be written as

SO[tex]_2[/tex](g)+Cl[tex]_2[/tex](g)⇌SO[tex]_2[/tex]Cl[tex]_2[/tex](g)

K=partial pressure of SO[tex]_2[/tex]Cl[tex]_2[/tex] ÷(partial pressure of SO[tex]_2[/tex] × partial pressure of Cl[tex]_2[/tex] )

Substituting all the given values, in the above equation, we get

6.9×10⁻⁶ = (0.760 bar × 0.760 bar)÷partial pressure of SO[tex]_2[/tex]Cl[tex]_2[/tex]

              = 4.3×10⁻⁸bar

To obtain a consistent increase in the organic solvent (usually methanol or acetonitrile) over the course of the study, gradients in reversed-phase HPLC typically use on-line (dynamic) mixing of solvents. This increases the elution strength of the eluent over time.
