Rank the following series of molecules or ions in order of decreasing bond energy using their bond order to predict relative mag
1 answer:
Answer:
P2>S2>Cl2 is the order of bond energy of the given molecules.
Explanation:
The bonding in each molecule is shown below:
Thus, between each P-atom, there exists a triple bond.
Between two S-atoms there exists a double bond.
Between two chlorine atoms, there exists a single bond.
As the number of bonds increases between the given atoms, then bond energy required to break the bonds also increases.
Thus, the bond order is shown below:

Explanation:
When water is frozen then it is known as ice and its state is solid. So, its molecules will be held closer to each other as they are held by strong intermolecular forces of attraction.
As a result, its temperature will be minimum as its molecules have least kinetic energy.
It is known that kinetic energy of a substance is directly proportional to temperature.
As, K.E =
where K.E = kinetic energy
T = temperature
k = boltzmann constant
When solid changes into liquid state then it means molecules of a substance has gained kinetic energy due to which there occurs more collisions between the molecules.
Hence, temperature of substance also increases.
Whereas when liquid state of a substance changes intro vapor state then it means that more kinetic energy has gained by the molecules due to which there will be much more collisions between the molecules.
Hence, temperature will be maximum in vapor state.
