Helium has a low latent heat of vaporization at 3.45 j/g. this indicates that helium has: strong attraction between solid particles weak attraction between solid particles strong attraction between liquid particles weak attraction between liquid particles

The heat of vaporization is when it changes phases from liquid to gas. When it is quite low, it means that it has weak attraction between the liquid particles

Option (d) is the correct answer.

Explanation:

When a unit mass of liquid is converted into vapor state without bringing any change in temperature then the heat required for this change in state is known as latent heat of vaporization.

So, when we say a compound has strong latent heat of vaporization then it means there is strong attraction between its molecules. Whereas weak latent heat of vaporization means there is weak attraction between molecules of a substance or compound.

Thus, we can conclude that helium has a low latent heat of vaporization at 3.45 J/g. This indicates that helium has weak attraction between liquid particles.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

b is the correct answer
