aleksklad [387]3 years ago
5 0

Answer:

C. is less than 0

Explanation:

The Gibbs free energy (G) of a system is defined as the energy that is used for the work done. The change in Gibbs free energy during a reaction shows the spontaneity and energetics of the reactions.

A reaction will be spontaneous if the change in Gibbs free energy will be negative or less than 0. Reactions with positive Gibbs free energy are non-spontaneous.

Hence, the correct answer is "C. is less than 0".

A vessel contained N2, Ar, He, and Ne. The total pressure in the vessel was 1100 torr. The partial pressures of nitrogen, argon,
geniusboy [140]

Answer:

Partial pressure Ne = 340 Torr

Option B

Explanation:

Gases contained in the vessel:

N₂, Ar, He, Ne

One of Dalton's law for gases determine this:

In a mixture of gases contained in a vessel, total pressure of the system must be the sum of partial pressure of each gas.

Total pressure = 1100 Torr

Let's replace:

Partial pressure N₂ + Partial pressure Ar + Partial pressure He + Partial pressure Ne  =  1100 Torr

Partial pressure Ne = 1100 Torr - Partial pressure N₂ - Partial pressure Ar  -Partial pressure He

Partial pressure Ne = 1100 Torr - 110 Torr - 250 Torr - 400 Torr

Partial pressure Ne = 340 Torr
