Problem
The following data present the temperatures at which certain vapor pressures are achieved for dichloromethane (CH2 Cl2 ) and methyl iodide (CH3 I):

Vapor Pressure (torr): 10.0 40.0 100.0 400.0
T for CH2 Cl2 (oC): -43.3 -22.3 -6.3 24.1
T for CH3 I(oC): -45.8 -24.2 -7.0 25.3

What quantity must be different for the two substances in order for this phenomenon to occur?
