4/4/2024 0 Comments Dry ice rate of sublimation![]() Solid CO2 (dry ice) sublimes at 195 K and its heat of sublimation (DHsubl) = 25.2 kJ/mol. (B) Change of water into ice- matter in solid state are more organized. Suppose we choose to maintain a constant pressure P 1 and gradually increase the temperature (starting from a sufficiently low temperature). Spontaneous, since equilibrium favors the sublimation into dry air ("dry" is the key word here). Spontaneity is favored by an increase in entropy. As a general rule, Dry Ice will sublimate at a rate of five to ten pounds every 24 hours in a typical ice chest. Therefore it gets the name "dry ice." sublimation of dry ice entropy Posted on Novem/ Knowing that the specific heat of water is 4.184 J g-1 Co, calculate the average ΔHsub/g CO2 and the average Δ Hsub/mol CO2. Phase changes are always accompanied by a change in the energy of a system. In option A, solid dissolves to form an aqueous solution and hence entropy increases. ![]()
