<u>Answer:</u> The standard change in Gibbs free energy for the given reaction is 4.33 kJ/mol
<u>Explanation:</u>
For the given chemical equation:
The expression of for the given reaction:
We are given:
Putting values in above equation, we get:
To calculate the standard Gibbs free energy, we use the relation:
where,
= standard Gibbs free energy
R = Gas constant =
T = temperature =
= equilibrium constant in terms of partial pressure = 0.174
Putting values in above equation, we get:
Hence, the standard change in Gibbs free energy for the given reaction is 4.33 kJ/mol
Answer:
Measure its mass
Measure its volume
Measure its number of moles
Explanation:
The noble gas configuration means that the electronic configuration for Lithium is written in shortcut by starting with the symbol for the nearest noble gas. Note that the noble gas should be lighter than the said element. In here, the nearest noble gas to Lithium is Helium (He). Then, add the additional electrons. Thus, the noble gas configuration would be: <em>[He]2s¹.</em>
Friction, applying the brakes, and wind
The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. ... This chemical series contains helium, neon, argon, krypton, xenon, and radon.
