Help please

If a closed system has the processes of condensation and evaporation occurring at the same rate under conditions of constant temperature we can assume _____. A) the container has zero pressure B) the container has a leak C) the liquid in the container is not water D) the contents are in the liquid and solid states E) the system has a specific vapor pressure The vapor pressure in a closed system at constant temperature has a linear dependence on temperature. A) True B) False The equation below _____. lnP = (-Delta H_vap/R) (1/T) + C A) is equal to the slope of the line achieved by plotting In P versus 1/T B) can be used to determine the enthalpy of vaporization once the slope of the line achieved by plotting In P versus 1/T is known C) can be used to determine the normal boiling point of a substance D) A and B E) B and C The molar heat of vaporization when compared to the molar heat of fusion for a particular substance is _____ A) always a smaller amount of ene
