Question 61-62

 

 

 

The diagram below represents two sealed, rigid containers and the conditions of pressure, volume, and temperature for each container. Container A is filled with N2(g) and container B is filled with O2(g).



 
 

61   Explain, in terms of the strength of intermolecular forces, why the gas in container B at standard pressure has a higher boiling point than the gas in container A at standard pressure.

Answer--> Container B has Stronger IMF  than container A

(Higher BP =strong IMFs)

62 In the space in your answer booklet , show a numerical setup for calculating the pressure if the gas in container B is cooler to standard temperature.
 

Answer--> 2 setups  PV/T=PV/T (must ignore container A)

(101.3kPa *750.0mL)/298K = (P x 750.mL)/273K

or since volume is constant

(101.3kPa)/298K = (P)/273K
