Explain Boyle's Law in terms of the kinetic molecular theory.

		Decreasing the volume means that at any one instant less molecules will collide with the walls of the container, which increases pressure.
		Decreasing the volume means that there are less gas molecules in the container, which increases pressure.
		Decreasing the volume means that at any one instant more molecules will collide with the walls of the container, which increases pressure.
		Decreasing the volume means that there are more gas molecules in the container, which increases pressure.

Solutions

Expert Solution

n= 3 means, it is the 3rd subshell

l = 2 means, "d" orbital

So, the answer is "3d"

In CF₄, both carbon and fluorine has 8 electrons outer shell. So, it follows octet rule.

In PF₅, fluorine has 8 electrons,but phosphorous has 10 electrons in outer shell. So, it does not follow octet rule.

In F₂, fluorine has 8 electrons outer shell. So, it follows octet rule.

In NF₃, both nitrogen and fluorine has 8 electrons outer shell. So, it follows octet rule.

So, answer is "PF₅"

Option-C

"Decreasing the volume means that at any one instant more molecules will collide with the walls of the container, which increases pressure."

Decreasing the volume means, the distance btween the walls of the container has decreased. So, that at any one instant molecules will make more collisions with the walls of the container, which increases pressure.

The answer is "1 sigma, 2 pi"

"P"

Phosphorus has IE₁ = 1012 IE₂ = 1900 IE₃= 18010 in KJ/mol

So, the answer is "P"
