The reaction quotient will be half of the equilibrium constant of the system.
<h3>Equilibrium constant</h3>
The term equilibrium constant refers to a number that shows the extent to which reactants are converted to products when the reaction has attained equilibrium. If the system is not at equilibrium, the number is called the reaction quotient.
If the reaction system is diluted to about twice its original volume, it follows that the reaction quotient will be halved with respect to the equilibrium constant hence the most likely value of the equilibrium constant is about half of the equilibrium constant.

According to Clausius-Clayperon equation,
is the vapor pressure at boiling point = 760 torr
is the vapor pressure at T_{2} =638.43 torr
Temperature
Δ
Plugging in the values, we get
ln
Therefore, the boiling point of octane = 389 K - 273 =
Shorter because the I-I bond in the I2 molecule is covalent whereas the bond between adjacent molecules is due to dispersion.
<h3>What is bond length?</h3>
Bond length typically falls between 0.1 and 0.2 nm. Covalent radius is the term used to describe the length of a connection formed between two comparable atoms. The order of the bond or the quantity of linked electrons between two atoms determines the bond length.
<h3>
What connection exists between the length and the strength of a bond?</h3>
The C-C bond in alkanes must be the longest since it is the weakest, and the C-C bond in alkynes must be the shortest because it appears to be the strongest, according to the data. We determined in the preceding section that the bond strength is inversely correlated to the bond length.
<h3>How can bond length be calculated in chemistry?</h3>
- The bond gets shorter as the atoms get smaller.
- The length of the bond decreases as bond multiplicity increases.
- The shorter the bond, the higher the effective nuclear charges of the bound atoms.

The answer is c.
There are 3 carbon atoms and six hydrogen atoms in a double-bond linear chain.
i.e.
H2C=CH-CH3
Answer:
a) [Tris0] : [Tris] = 1 : 100
b) Range = 7.1 to 9.1
Explanation:
a) Calculation of ratio of the basic and the acidic forms of tris
pH of a buffer is calculate using Henderson-Hasselbalch equation
Conjugate acid of Tris dissociated as
For tris,
Salt or Basic form = tris0
Acid or Acidic form = Tris
pKa = 8.1
pH = 6.1
[Tris0] : [Tris] = 1 : 100
b) Range of Tris
Range of any buffer is:
From (pKa -1) to (pKa+1)
So, range of Tris is:
From (8.1 - 1) to (8.1 +1)
or from 7.1 to 9.1
