What would the Kc value be from this reaction: H2 + I2 = 2HI.

Chemistry

Darya [45]3 years ago

Answer: The value of K_{c} for the given reaction is  K_{c} = \frac{[HI]^{2}}{[H_{2}][I_{2}]} .

Explanation:

The ratio of concentration of products and reactants raised to the power of their concentration is called equilibrium constant.

It is denoted by the symbol 'K_{c}'.

For example, H_{2} + I_{2} \rightarrow 2HI

The expression for K_{c} of this reaction is as follows.

K_{c} = \frac{[HI]^{2}}{[H_{2}][I_{2}]}

So, by putting the respective concentrations of the species involved in the reaction it is possible to determine the value of K_{c} for the given reaction.

Thus, we can conclude that the value of K_{c} for the given reaction is  K_{c} = \frac{[HI]^{2}}{[H_{2}][I_{2}]} .

What is the difference in concentration between a pH of 7 and 12?
Ratling [72]

Answer:

The pH of a solution is simply a measure of the concentration of hydrogen ions,  

H

+

, which you'll often see referred to as hydronium cations,  

H

3

O

+

.

More specifically, the pH of the solution is calculated using the negative log base  

10

of the concentration of the hydronium cations.

Now, we use the negative log base  

10

because the concentration of hydronium cations is usually significantly smaller than  

1

.

As you know, every increase in the value of a log function corresponds to one order of magnitude.

In the citric acid cycle, ATP molecules are produced by _____. In the citric acid cycle, ATP molecules are produced by _____. su
monitta

Answer:

substrate-level phosphorylation

Explanation:

Substrate-level phosphorylation is the metabolic reaction which results in formation of energy currency molecules, ATP or GTP by direct transfer of a phosphoryl group to the ADP or GDP from the another phosphorylated compound.

<u>In citric acid cycle, Succinyl-CoA in the presence of succinyl-CoA synthase is converted to succinate. Condensation reaction (Substrate-level phosphorylation) of GDP and Pi takes place which results in the formation of GTP.</u>
