44) Which of the following statements concerning evaporation is correct?

C) be a very “explosive” substance

D) have strong attractive forces between molecules

 

46) The vapor pressure of SnCl4 reaches 400 mm Hg at 92 °C, the vapor pressure of SnI4 reaches 400 mm Hg at 315 °C, the vapor pressure of PBr3 reaches 400 mm Hg at 150 °C, and the vapor pressure of PCl3 reaches 400 mm Hg at 57 °C. At 175 °C, which substance would have the lowest vapor pressure?

A) PBr3

B) SnI4

C) SnCl4

D) PCl3

 

47) What effect will decreasing the temperature of a liquid by 15 °C at constant pressure have on the magnitude of its vapor pressure?

A) increase

B) decrease

C) no change

D) insufficient information given

48) The boiling point of a liquid is ________.

A) the temperature at which the rate of sublimation and evaporation are equal

B) always 100 °C or greater

C) the temperature at which the vapor pressure of the liquid equals the pressure over the liquid

D) the temperature at which sublimation occurs

 

49) Which statement about the boiling point of water is incorrect?

A) The boiling point is greater than 100 °C in a pressure cooker.

B) The boiling point is less than 100 °C for locations at low elevations.

C) At sea level and at a pressure of 760 mm Hg, the boiling point is 100 °C.

D) In a pressure cooker, shorter cooking times are required due to the change in boiling point.

 

50) The normal boiling point of a substance is determined by its molecular mass and its intermolecular forces. Considering these two factors, predict the order of increasing boiling points for the following substances:               CH4, CS2, KBr, NH3.

A) CS2 < CH4 < KBr < NH3 B) CH4 < CS2 < NH3 < KBr C) NH3 < KBr < CS2 < CH4 D) CH4 < KBr < NH3 < CS2
