Graph of Vapor Pressure and Temperature
« on: February 18, 2008, 09:47:24 PM »
Hi, I have a really tough question about some chemistry. I really don't want someone just to do it, I really need this explained as well. Can you please help me with this?
"Construct a graph of vapor pressure (in Pa) vs. temperature (in Kelvin) for water between 273 K and 373 K. Do this by using the Clausius-Clapeyron equation to evaluate the vapor pressure at inverbals of 10 K across the range, giving you 11 data points."
where P is measured in Pa, Delta Hvap = 42.855 kJ/mol and C=25.3412

also, in know the C-C euqation is lnP=-deltaHvap/R(1/t)+c, but am a bit confused what this information refers to directly.

Can you be more specific about what you don't understand?
