Compound with lowest boiling point
As can be seen from the above plot of the logarithm of the vapor pressure vs. the temperature for any given pure chemical compound, its normal boiling point can serve as an indication of that compound's overall volatility. A given pure compound has only one normal boiling point, if any, and a compound's normal boiling point and melting point can serve as characteristic physical properties fo… WebNov 30, 2024 · With the Clausius-Clapeyron equation is possible to determine the boiling point of any substance at a given pressure. Let's take a closer look: \small ln\left (\cfrac {P_1} {P_2}\right) = \cfrac {-\Delta H} {R} \ \times \left (\cfrac {1} {T_1} - \cfrac {1} {T_2}\right) ln(P 2P 1) = R−ΔH × (T 11 − T 21) where: P_1 P 1 — Pressure at state 1; P_2 P 2
