derive the relationship. ln(p2/p1) = - (H(vap [ (1/T2) – (1/T1) ] (5.2) R . Note that this is a more useful than the equivalent expression given by Equation 4.12 of Atkins. b) The vapor pressure of pure nitric acid (HNO3) is pvap = 47.9 torr at T = 20.0 (C, and pvap = 208. torr at T = 50.0 (C. Using equn 5.2, estimate the value for (H(vap ... ................
