Question

(a) Consider a gaseous mixture of N2 and CO and compare it with a gaseous mixture of N2 and Ar. Which mixture is more likely to follow Amagat's Law? Why? Consider a diatomic molecule such as carbon monoxide. What is meant by the force constant of the C-O bond? How is it measured? Why is the heat capacity of CO significantly larger than that of argon?

Answer 1

a)The mixture of nitrogen and carbon monoxide will be less stable than the mixture of nitrogen and argon. This is because Argon is a noble gas and inert as compared to carbon monoxide which is more reactive than argon. And we know that Amagat's law is strictly obeyed by ideal gas mixtures in which gases do not react with each other.

So the Amagat's law will be obeyed by Nitrogen and Argon mixture as follows

V_{​​​​​​Total} =V_{​​​​​​N2.} +V_{​​​​​​Ar}

Only first question as per as q n a guidelines.sorry
