Q1. Boiling points Taking the last digit of your student ID number as a key, select the corresponding solvent from the table below. Assume you are using that solvent for the following questions. solve the first one Carbon disulphide
ID numbe Solvent boiling point (1 atm) ÎvapH° / °C /kJ mol-1 0,1 Carbon disulphide 46.3 26.7 2,3 Carbon tetrachloride 76.7 30.0 4,5 Cyclohexane 80.7 30.1 6,7 Diethylether 34.6 27.1 8,9 Acetone 56.0 31.3
(a) Compute the entropy of vaporisation of this solvent. (Briefly, compare the value you obtain with that from Troutonâs rule (ÎvapS° â10.5 R). answer this qustion)
Entropy of vaporization= 0.08362 kJ mol-1/K
Entropy of vaporization= 83.62 J mol-1/K
(b) Use the tabulated experimental value of ÎvapH° to estimate the partial pressure (i.e. vapour pressure, in atm) of that solvent at room temperature (25 °C). What implications does this have for safe storage and handling of the solvent?answer this qustion)
