Answer to Question #183081 in General Chemistry for Katrina Peralta

Question

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

= 298 + 173

= 571

= 571/2

= 285.5 K

285.5 - 273

= 8.5°C
