The quantity which is equivalent to the product of the absolute index of refraction of water and the speed of light in water system is the speed of light in vacuum.
<h3>What is the speed of light?</h3>Speed of light is the rate of speed though the light travels. To find the speed of light in any medium, the following formula is used.
Here, (n) is the index of reaction and (c) is the speed of light in the vacuum. The speed of light in the vacuum is almost equal to the 3.0×10⁸ m/s.
Now the quantity which is equivalent to the product of the absolute index of refraction of water and the speed of light in water has to be find out.
The above formula can be written as,
Here, the product of index of refraction and speed of light is equal to the speed of light in vacuum. This will be true for water as well.
Thus, the quantity which is equivalent to the product of the absolute index of refraction of water and the speed of light in water system is the speed of light in vacuum.

<u>Answer:</u> The partial pressure of the are 0.352 atm, 0.352 atm and 0.408 atm respectively.
<u>Explanation:</u>
We are given:
Relation of with
is given by the formula:
Where,
= equilibrium constant in terms of partial pressure = ?
= equilibrium constant in terms of concentration =
R = Gas constant =
T = temperature =
= change in number of moles of gas particles =
Putting values in above equation, we get:
The chemical reaction for the decomposition of phosgene follows the equation:
At t = 0 0.760 0 0
At 0.760-x x x
The expression for for the given reaction follows:
We are given:
Putting values in above equation, we get:
Negative value of 'x' is neglected because partial pressure cannot be negative.
So, the partial pressure for the components at equilibrium are:
Hence, the partial pressure of the are 0.352 atm, 0.352 atm and 0.408 atm respectively.
