The vapor pressures of two crystalline molecular solids are listed below.
Temperature (°C) | PC (torr) | PD (torr)
25 | 1.2 | 0.08
45 | 15 | 0.90
(a) Calculate the factor by which the vapor pressure of each solid increases when the temperature is raised from 25 °C to 45 °C.
(b) Using the data and your calculations, identify which solid has stronger intermolecular forces and briefly justify your answer.
