Suppose you heat up an unknown substance, which bubbles up upon reaching a temperature of 45.5\deg C. If the unknown substance has a \Delta H_(vap)=30.8k(J)/(m)ol, at what temperature would you expect the vapor pressure of the substance to be 448 mmHg ?
=318.5,P_(2)=448mmHg_(9),P_(1)=760mmHg,T_(2)?
