Answer
- continuous removal of PH3
- adding more of P into the system
Explanation:
In the reaction P4(g)+6H2(g) ⇌ 4PH3(g);
- The effect of temperature on equilibrium has to do with the heat of reaction. Recall that for an endothermic reaction, heat is absorbed in the reaction, and the value of ΔH is positive. Thus, for an endothermic reaction, we can picture heat as being a reactant:
heat+A⇌BΔH=+
- Since the reaction is endothermic reaction, heat is a absorbed. Decreasing the temperature will shift the equilibrium to the left, while increasing the temperature will shift the equilibrium to the right forming more of PH3.
- According to Le Chatelier’s principle, adding additional reactant to a system will shift the equilibrium to the right, towards the side of the products. In the same Way, reducing the concentration of the product will also shift equilibrium to the right continually forming PH3 as it is removed.
Explanation:
At each reflecting surface (benzene and glass) there will be 180 degree phase change.
Now, for constructive interference the optical path in benzene is
.
Formula to calculate thickness of a benzene thin film is as follows.
Optical path length through benzene (
) = ![2 \times n \times d](https://tex.z-dn.net/?f=2%20%5Ctimes%20n%20%5Ctimes%20d)
Hence, substituting the given values into the above formula as follows.
Optical path length through benzene = ![2 \times n \times d](https://tex.z-dn.net/?f=2%20%5Ctimes%20n%20%5Ctimes%20d)
d = ![\frac{\text{Optical path length through benzene}}{2 \times n}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BOptical%20path%20length%20through%20benzene%7D%7D%7B2%20%5Ctimes%20n%7D)
=
=
(as 1 nm = ![10^{-9}m](https://tex.z-dn.net/?f=10%5E%7B-9%7Dm)
= 204.9 m
Thus, we can conclude that minimum thickness of benzene is 204.9 m.
Determine the density.
Explanation:
The best procedure a student can use to examine the intensive property of a rectangular block of wood is to determine its density.
An intensive property is a property of matter that is independent of the amount of matter present in it. Examples are density, melting point, boiling point etc.
Every substance in pure form have their distinct density. It is without regards to the mass and volume of such substance present.
Mass, length and volume are extensive properties that depends on amount of matter present.
