Answer:
Keq = 0.053
7.3 kJ/mol
Explanation:
Let's consider the following isomerization reaction.
glucose 6‑phosphate ⇄ glucose 1 - phosphate
The concentrations at equilibrium are:
[G6P] = 0.19 M
[G1P] = 0.01 M
The concentration equilibrium constant (Keq) is:
Keq = [G1P] / [G6P]
Keq = 0.01 / 0.19
Keq = 0.053
We can find the standard free energy change, ΔG°, of the reaction mixture using the following expression.
ΔG° = -R × T × lnKeq
ΔG° = -8.314 J/mol.K × 298 K × ln0.053
ΔG° = 7.3 × 10³ J/mol = 7.3 kJ/mol
Answer:
Explanation:
Melting: it is a phase change from solid to liquid. It is usually attained when a substance reaches it melting point as heat is supplied to it. The vibrating particles break loose and begins to move like a liquid. Melting of iron is an example.
Boiling; is a phase change from liquid to gases. When substances reaches their boiling points when heat is supplied they begin to boil and form gases. An example is the boiling of water. Boiling usually occurs when the vapor pressure is equal to the atmospheric pressure around.
Condensing: is a phase change from gas to liquid. When gases are cooled they condense back to liquid. Example is rain clouds.
Freezing: is a phase change from liquid to solid.
Your answer cannot be MORE precise than the least precise measurement. The following rule applies for multiplication and division: The LEAST number of significant figures in any number of the problem determines the number of significant figures in the answer.
Answer:
Belgium and the Netherlands swap land near Lanaye and Oost-Maarland over the discovery of a headless body several years prior, which the Belgian Authorities could not access without crossing Dutch territory. The border has been straightened out and now runs down the center of the Meuse River.[5] The change took effect on 1 January 2018.
