The normal boiling temperature of diethyl ether, (C 2 H 5 ) 2 O , is 307.7 K and the standard enthalpy of vaporization is 27.4 kJ mo * l ^ - 1 Use the Clausius-Clapeyron equation to predict the vapour pressure of liquid diethyl ether at 289.49

Vapour Pressure vs 1/T - DeltaHvap - Clausius Clapeyron Equation   The standard enthalpy of vaporization (H°vap) of acetone ((CH3)2CO) is 32.0 kJ/mol. The normal boiling point of acetone is 56.5°C. Calculate the vapour pressure of acetone at 33.5°C.

Acetone has a vapour pressure of 53.3 kPa at 39.5 °C and 202.6 kPa at 78.6 °C. From the above data, obtain an equation to correlate the vapour pressure of acetone. (The equation should be in the form In(P)= -A/T + Co where P, is in kPa units. Find numerical values for A and Co) A= 5756 K, Co = 17.989 A= 4756 K, Co = 16.989 A= 3756 K, Co = 15.989 A= 2756 K, Co = 14.989

Calculate the vapor pressure of ethanol at 105.00 if the normal boiling temperature of ethanol is 78.50 and the molar enthalpy change of vaporization is equal to 40.5 kJ mol-1.
