Answer:
Butanoic acid.
Explanation:
Hello,
In this case, when a primary alcohol such as 1-butanol (OH is bonded to a primary carbon) is oxidized in the presence of a strong oxidizing media such as potassium dichromate (K2Cr2O7) and sulfuric acid, the stepwise oxidation goes to the corresponding aldehyde with a further oxidation to the corresponding carboxylic acid:
Therefore, on the attached picture you can find that the formed aldehyde is butanal and the inly organic product, due to the strong oxidizing media is finally butanoic acid.
Best regards.
The equilibrium constant of the reaction is 0.323.
Equilibrium constant:
It is expressed as the ratio of concentration of the products to the concentration of reactants. It is represented by K.
The relationship of K with G (Gibbs free energy) is expressed as:
G° = -RTlnK
Here R is the gas constant, T is the temperature.
Calculations:
Convert 25°C to K.
25°C = (25 + 273.15) K
= 298.15 K
Substitute the values in the above expression.
2.8 x 1000 J/mol = -8.314 J/mol.K x 298.15 K x ln(K)
lnK = 2800 J/mol/(-8.314 J/mol.K x 298.15 K)
lnK = -1.13
K = e^-1.13
= 0.323

Answer:
4.78atm
Explanation:
From the question, we obtained the following:
P1 (initial pressure) = 3.5 atm
T1 (initial temperature) = 200K
T2 (final temperature) = 273K
P2 (final pressure) =?
Using P1/T1 = P2/T2, the final pressure can be obtained as shown below:
P1/T1 = P2/T2
3.5/200 = P2/273
Cross multiply to express in linear form as shown below:
200 x P2 = 3.5 x 273
Divide both side by 200
P2 = (3.5 x 273)/200
P2 = 4.78atm
Therefore, the pressure at 273K is 4.78atm
