The CO2 sublimation heat is 16.2 kJ/mol and the entropy value of sublimation is 88.5 joules/mol. k (What temperature does CO2 sublimate at?

Oxygen (O₂) is necessary for cellular respiration; it must be transported from the lungs to tissues through the bloodstream. However, O₂ is not very soluble in water. The Keq of oxygen dissolving at 300.0 K is 7.64 x 10⁻⁴ and the Keq at 320.0 K is 5.23 x 10⁻⁴. Calculate the ∆H(dissolve) for oxygen solubility in water, in kJ/mol.

HI has a normal boiling point of –35.4°C, and its DHvapis 21.16 kJ/mol. Calculate the molar entropy of vaporization (DSvap).  Be sure to include the correct units with your answer.

What is AS for the following reaction? 2Cl2(g) + SO2(g) SOCI₂(g) + Cl₂O(g) Substance: Cl₂(g) SO2(g) SOCI2(g) C1₂O(g) 223.0 248.1 309.8 266.1 S(J/K. mol):

Calculate the entropy change of 63.4 g of water that freezes into ice at 273.15 K. AHfus for water is 6.01 kJ/mol. J/K

Read the descriptions of physical or chemical changes in the table below. Then decide whether the change will be spontaneous, if you can. Change During an endothermic chemical reaction, four moles of gaseous reactants are turned into two moles of gaseous products. A solid precipitates from a solution, releasing heat as it does so. A solid absorbs heat and turns to a gas. Is this change spontaneous? Yes. O No. O Can't decide with information given. O Yes. O No. O Can't decide with information given. O Yes. O No. O Can't decide with information given.

What is entropy, S, and how is entropy related to spontaneous change?

Determine the total entropy change when 15.00 g of ice at –15°C is heated to 75°C. The molar heat of fusion of ice is 6.02 kJ/mol, and its specific heat is 2.11 J/g °C. The specific heat of water is 4.184 J/g °C

Read the descriptions of physical or chemical changes in the table below. Then decide whether the change will be spontaneous, if you can. Change Two liquids mix, neither absorbing nor releasing heat. During an endothermic chemical reaction, a gas is consumed and a liquid produced. An endothermic chemical reaction between two liquids results in gaseous products. Is this change spontaneous? Yes. O No. O Can't decide with information given. Yes. O No. O Can't decide with information given. O Yes. O No. O Can't decide with information given.
