Gibb's free energy, ΔG°, is related to the equilibrium constant of the reaction, K, through the equation:
ΔG°= RT(ln K)
By definition, K is the ratio of the equilibrium partial pressure of the products to the reactants, raised to the power of their stoichiometric coefficients, respectively. For this reaction,
N₂ (g) + 3 H₂ (g) → 2 NH₃<span> (g)
the equilibrium constant is
K = [NH</span>₃]²/[N₂][H₂]³
Assuming that the given partial pressures are the equilibrium pressures, then we can substitute them directly:
K = [0.65 atm]²/[1.9 atm][1.6 atm]³
K = 0.05429 atm⁻²
Then, we can using this value to find ΔG. Note that R is the gas constant equal to 0.08206 L-atm/mol-K.
ΔG°= (0.08206 L-atm/mol-K)(298 K)(ln 0.05429 atm⁻²)
ΔG° = -71.244 L-atm/mol
From the image shown, the uncertainty in the weighing balance extends to the hundredth place.
<h3>What is a balance?</h3>
A balance is any device that is used for measuring the mass or weight of an object. The balance is a necessary instrument in every laboratory.
Looking at the image shown, the following are true;
- the uncertainty is in the hundredth place.
- a mass that falls between 1 gram and 9 grams measured on this balance will always have 3 significant figures.

Answer:
This effect is caused by increased levels of carbon dioxide, chlorofluorocarbons and other gases in the air, many of them released by human activity. greenhouse effect The warming of Earth's atmosphere due to the buildup of heat-trapping gases, such as carbon dioxide and methane.
Explanation:
Answer:
Explanation:
The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than a liquid or solid
Answer:
San Diego boasts top crops in nursery, flowers, avocados, tomatoes, citrus, chickens & eggs, shrooms, succulents, strawberries, coffee & cannabis. Most of San Diego County farms are small 1-9 acre proprieties, and that awards San Diego County more certified organic growers than any other county in the nation.
