Question

Choose the substance with the highest vapor pressure at a given temperature.

Answer 1

BF3 .... BP = −100.3 °C 
RbCl ..... solid 
CH3SCH3 ..... BP = 35-41 °C 
SbH3 .... BP = −17 °C 
SiS2 ..... solid 


Ethanol solid --> ethanol melts --> ethanol liquid 
-135C ---------------> -114C --------------> -50C 
............ ΔT = 21C ....... ....... ΔT = 64C
