Purpose: Use experimental techniques to record temperature and volume data for known and unknown compounds. The liquid and gas are going to be at equilibrium. We will also determine the boiling point for the known and unknown. Then use a graph to calculate the slope and then use Clasius- Clapeyron equation to find the heat vaporization.
Procedure: Refer to pages 155-167 of Chemistry 1210 General Chemistry Laboratory Manual Hayden- McNeil Publishing Inc. 2012-2013
Report Sheet: See attached report sheet and graphs.
Sample Calculations:
1/t= 35 C +273 K = 1/308 =0.0325 1/K
Ps= Pb (1- Vr/V * T/Tr)= 746(1-5/8*308.15/343.15)=325.3
