the deltag value for the acontinase reaction is 5.8 kj/mol. what is the ratio of isocitrate/citrate understandard conditions?

soldi70 [24.7K]

The ratio of isocitrate/citrate under standard conditions is 0.096 when the value of ΔG° is given by 5.8kj/mol.

We know that isocitrate and citrate are convertible. It is given that the ΔG° is given by 5.8kj/mol. Then we know that,

ΔG° = -RTlnK

lnK = -RT/ΔG°

On substituting the values, we get

lnK = -5.6x10³/(6.314x296)

lnK = -2.34

K = 0.09623

The value of k is 0.09623.

Therefore, the ratio of Isocitrate to citrate is given by,

[Isocitrate]/[Citrate] = 0.09623

The ratio could be however rounded off to 0.096.

Therefore, the ratio is given by 0.096 for the isocitrate/citrate under standard conditions. In this way, the ratio could be computed very easily.

What is the empirical formula of vitamin A ( C=83.85, H=10.56, O=5.58)<br>

ladessa [460]

The empirical formula of vitamin A : C₂₀H₃₀O

<h3>Further explanation </h3>

The empirical formula is the smallest comparison of atoms of compound =mole ratio of the components

The principle of determining empirical formula

Determine the mass ratio of the constituent elements of the compound.
Determine the mole ratio by dividing the percentage by the atomic mass

mol ratio of C : H : O ⇒

$\tt \dfrac{83.85}{12}\div \dfrac{10.56}{1}\div \dfrac{5.58}{16}\\\\6.9875\div 10.56\div 0.34875\rightarrow divide~by~smallest(0.34875)\\\\20\div 30\div 1$

2. A 0.5 kg tennis ball has speed of 15m/s. what is the kinetic energy of tennis?

Talja [164]

Explanation:

Given

mass (m) = 0.5 kg

velocity (v) = 15 m/s

Now

Kinetic energy

= 1/2 *m*v²

= 1/2 * 0.5 * 12²

= 0.5 *0.5 * 144

= 36 joule

Nitrogen (atomic number 7) and phosphorus (atomic number 15) belong to group 15 of the Periodic Table. Write the electronic conf

scoundrel [369]

Answer:

Electronic configuration of nitrogen: K=2 L=5

Electronic configuration of phosphorus : K = 2 L = 8 M = 5

The element nitrogen will be more electronegative because of the smaller size of its atom. nitrogen accepts electrons more easily.
