Which of the following can be determined by the Clausius-Clapeyron equation? ² (12-1) In P₂ -AH, vap P₁ = R Choose one: The vapor pressure of a liquid at a given temperature. The boiling point of a liquid at a given pressure. The standard enthalpy of vaporization of a liquid by measuring vapor pressure at different temperatures. All of these can be determined using the Clausius-Clapeyron equation. Which of the following statements about vapor pressure are TRUE? Choose one: The higher the vapor pressure at room temperature for a liquid, the higher the boiling point for that liquid. OIf two liquids have the same boiling point at 1 atm., then they must have the same enthalpy of vaporization. O Increasing temperature will always increase vapor pressure. O The Clausius-Clapeyron equation can only be used when pressure is in units of atmospheres.
