What is true for all exergonic reactions?

Chemistry
1 answer:
vovangra [49]3 years ago
4 0

Answer:

The reaction proceeds with a net release of free energy.

Explanation:

Exergonic reactions: It is known as the chemical reaction where the change in the free energy is occur negative or there is a net release of free energy, and indicating a spontaneous reaction. For the processes this takes place under constant temperature, and pressure conditions.

The Gibbs free energy is used whereas the processes which takes place under constant volume, and temperature conditions, and their Helmholtz energy is used. Cellular respiration is the example of an exergonic reaction.

If 1.00 mol of argon is placed in a 0.500-L container at 29.0 ∘C , what is the difference between the ideal pressure (as predict
Mashcka [7]

Answer:

Ideal ,P=49.52 atm

Real ,P=47.62 atm

Explanation:

Given that

n= 1 mol

V= 0.5 L

T= 29  ∘C = 29 +273 K

T= 302 K

For ideal gas

P V = n R T

P x 0.5 = 1 x 0.0821  x 302

P=49.52 atm

For real gas

\left ( P+\dfrac{an^2}{v^2} \right )\left ( v-nb \right )=nRT

Now by putting the values

\left ( P+\dfrac{1.345\times 1^2}{0.5^2} \right )\left ( 0.5-1\times 0.03219 \right )=1\times 0.0821\times 302

\left ( P+\dfrac{1.345}{0.5^2} \right )=53

P=47.62 atm

How many atoms in each elemental sample?
eduard

Answer:

2.9 × 10²⁴ atoms Cu; 3.3 × 10²¹ atoms C; 1.44 × 10²⁵ atoms Hg; 9.63 × 10²² atoms Na

Explanation:

To convert moles to atoms, we need a conversion factor: Avogadro's number. There are 6.02 × 10²³ atoms in 1 mole of atoms.

4.9 mol Cu × 6.02 × 10²³ atoms Cu/1 mol Cu = 2.9 × 10²⁴ atoms Cu

5.4 × 10⁻³ mol C × 6.02 × 10²³ atoms C/1 mol C = 3.3 × 10²¹ atoms C

24.0 mol Hg × 6.02 × 10²³ atoms Hg/1 mol Hg = 1.44 × 10²⁵ atoms Hg

0.160 mol Na × 6.02 × 10²³ atoms Na/1 mol Na = 9.63 × 10²² atoms Na

Rank the following chemical species from lowest absolute entropy (So) (1) to highest absolute entropy (5) at 298 K?
kramer

Answer:

Rank the following chemical species from lowest absolute entropy (So) (1) to highest absolute entropy (5) at 298 K?

a. Al (s)

b. H2O (l)

c. HCN (g)

d. CH3COOH (l)

e. C2H6 (g)

Explanation:

Entropy is the measure of the degree of disorderness.

In solids, the entropy is very less compared to liquids and gases.

The entropy order is:

solids<liquids<gases

Among the given substances, water in liquid form has a strong intermolecular H-bond.

So, it has also less entropy.

Next acetic acid.

Between the gases, HCN, and ethane, ethane has more entropy due to very weak intermolecular interactions.

HCN has slight H-bonding in IT.

Hence, the entropy order is:

Al(s) < CH3COOH (l) <H2O(l) < HCN(g) < C2H6(g)
