A student determines the heat of dissolution of solid cesium sulfate using a coffee-cup calorimeter of negligible heat capacity. When 16.2 g of Cs₂SO4(s) is dissolved in 101.00 g of water, the temperature of the solution drops from 25.00 to 23.12 °C. Based on the student's observation, calculate the enthalpy of dissolution of Cs₂SO4(s) in kJ/mol. Assume the specific heat of the solution is 4.184 J/g°C.

Consider the interconversion of A and B. Suppose in the absence of an enzyme, the forward rate constant KF is 104 s¹ and the reverse rate constant KR is 106 S¹. Calculate the equilibrium constant K. How would the presence of an enzyme affect the value of K? K
. These resins are organic polymeric networks that contain functional groups that are permanently attached to the resin. One such functional group is sulfonic acid, -SO3H. When placed in water, the resin (being a large organic molecule) will not dissolve. However, the ionic functional groups become hydrated and the resin will swell as it takes up waters of hydration. The resin may then be thought of as a solid solution mixture with the functional groups being "dissolved" but the polymer remaining as a solid. The hydronium ion (H3O+) associated with acidic functional groups like sulfonic acid will dissociate just as it would if the acid were free of the resin. If other cations such as Cu2+ or Na+ are added to the resin, an ion-exchange reaction can occur: . Note that one H+ is released for each positive charge bound to the resin. Since the resin exchanges a hydrogen ion for a sodium ion in this reaction, sulfonic acid resins are called cation-exchange resins. Equilibrium constants may…

Curved line up from 105 K at 10 to the power of 0 Pa up to 200 K and 10 to the power of 6 Pa. The line forks here. There is an almost vertical line up to 10 to the power of 8 Pa, and a line that goes diagonally up and to the right to 325 K and 10 to the power of 7 Pa. To the left of the fork is "Solid". To the right of the fork is "Gas". In between the lines of the fork is "Liquid". End of image. The pressure is decreased slowly from 107 Pa at 150 K. Which of these best describes what is observed?
