Answer to Question #185435 in General Chemistry for Zin

Question

2. Based from the phase diagrams of water and carbon dioxide, answer the following questions and justify your answers: 1. You have ice at 263 K (-10.0 oC) and 1.0 atm. What could you do to make the ice sublime? 2. A sample of dry ice (solid CO2) is cooled to 173 K (-100.0 oC), and is set on a table at room temperature (298 K; 25 oC). At what temperature is the rate of sublimation and deposition the same (assume that pressure is held constant at 1 atm)?

Answer 1

Temperature at which sublimation and deposition the same =194.65 K
