Answer:
New Volume = 0.013 Liter
Explanation:
Combined Gas Law Problem
P₁V₁/T₁ = P₂V₂/T₂
P₁ = 1 atm
V₁ = 1.2 Liters
T₁ = 0°C = 273 K
P₂ = 100 atm
V₂ = V₁(P₁/P₂)(T₂/T₁)
T₂ = 15°C = (273 + 15)K = 288K
P₂ = 1.2L(1atm/100atm)(288K/273K) = 0.013 Liter
Why are Acetyl-CoA and succinyl-CoA, both high energy thioesters, chemical energies put to different uses?
The energy released by hydrolysis of acetyl-CoA is needed for the condensation reaction that links acetyl moiety to oxaloacetate, yielding citrate. The energy released by hydrolysis of succinyl-CoA drives the phosphorylation of GDP, yielding GTP
Some reactions of the citric acid cycle are endergonic. Explain how the overall cycle is exergonic.
The sum of the energies of the individual reactions is -44.3kJ for each mole of acetyl-CoA that enters the cycle
Which enzymes of the citric acid cycle are missing from the glyoxylate cycle?
isocitrate dehydrogenase, alpha-ketoglutarate dehydrogenase, and succinyl-CoA synthetase
Answer : The concentration of and at equilibrium is, 0.0031 M and 0.0741 M respectively.
Explanation : Given,
Moles of = 0.166 mol
Volume of solution = 2.15 L
First we have to calculate the concentration of
Now we have to calculate the concentration of and at equilibrium.
Initial conc. 0.0772 0 0
At eqm. 0.0772-x x x
The expression for equilibrium constant is:
By solving the term, we get the value of 'x'.
x = 0.0741
Thus,
The concentration of at equilibrium = (0.0772-x) = (0.0772-0.0741) = 0.0031 M
The concentration of at equilibrium = x = 0.0741 M
