Which 1-mole sample has the least entropy?

Chemistry
1 answer:
Alexus [3.1K]3 years ago

<span>The correct answer is option 1. Entropy is the degree of disorderliness in a system. Among the phases, solid has the most ordered structure. Also, at lower temperatures the molecules will have less kinetic energy therefore less motion. Thus, bromine in solid form at 266K has the least entropy.</span>

Dinitrogentetraoxide partially decomposes into nitrogen dioxide. A 1.00-L flask is charged with 0.0400 mol of N2O4. At equilibri
artcher [175]

Answer:

Keq=0.866

Explanation:

Hello,

In this case, the undergone chemical reaction is:

N_2O_42NO_2

In such a way, since 0.0055 mol of N₂O₄ remains in the flask, one infers that the reacted amount (x) was:

x=0.04mol-0.0055mol=0.0345mol

In addition, the produced amount of NO₂ is:

2*0.0345mol=0.069mol

Finally, considering the flask's volume, the equilibrium constant is then computed as follows:

Keq=\frac{(2*0.0345M)^2}{0.0055M}=0.866

Best regards.

Define and explain each trend.
Romashka [77]
Atomic radius- a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding cloud of electrons.
Electron Affinity-the electron affinityof an atom or molecule is defined as the amount of energy released or spent when an electron is added to a neutral atom or molecule in the gaseous state to form a negative ion.
Electronegativity-a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used. Fluorine (the most electronegative element) is assigned a value of 4.0, and values range down to caesium and francium which are the least electronegative at 0.7.
Lonization energy- qualitatively defined as the amount of energy required to remove the most loosely bound electron, the valence electron, of an isolated gaseous atom to form a cation.
