Title: What is the vapor pressure of acetone at 48.7 C?
Post by: Calicum on June 08, 2012, 12:57:18 PM

What is the vapor pressure of acetone at 48.7 C?

Using Clausius-Clapeyron equation:

ln(p1/p2) = ΔHvap/R(1/t2-1/t1)

p1 = 760 torr
p2 = ???
t1 = 56.5 C
t2 = 48.7 C
ΔHvap = 32 KJ/mol
R = 0.0083 KJ/mol

I keep getting the wrong answer, please help.
