Question

The statements in the following multiple choices deal with various aspects of the relationship between vapor pressure and intermolecular forces. Choose the statement which is true. a) Water which is boiling vigorously is at a higher temperature than water which is boiling slowly. b) Water which is boiling vigorously is at the same temperature as water which is boiling slowly. c) At a given temperature solid SF_G has lower vapor pressure than solid I_2. d) CHBr_3 is more volatile than CHCI_3 e) At a given temperature liquid NH_3 has higher vapor pressure than liquid PH_3 Shown above is a phase diagram for O_2 (not drawn to scale). Use this phase diagram to correct statement from the following multiple choices. a) At T = 27.10 K and P = 24.90 atm O_2 exists as part solid, part liquid. b) At T = 55.2 K and P = 1 atm O_2 exists only in the solid phase. c) The point at T = 154.2 K and P = 49.8 atm is called the triple point. d) The point at T = 90.2 K and P = 1 atm is called the critical point. e) The point at T = 55.2 K and P = 1 atm is called the normal melting.

Explanation / Answer

5 . D (NH3 will have high vaopur pressure and boling point than PH3 due to presence of strong H-Bonding)

6. B ( at T= 55.2 K and P = 1 atm it exist as solid phase)

comment= Triple point = 55.2K, critical temp = 154.2K (check phase diagram)
