Iâm not sure, but question 3 might have more then one answer.
2. The value of ÎHsoln for a water soluble compound is +34 k1mol, which value for this compound would be numerically larger, its lattice energy or its hydration energy? Select the single best answer. The hydration energy, because it is the endothermic step. The lattice energy, because it is the endothermic step. The hydration energy, because it is the exothermic step. The lattice energy, because it is the exothermic step. a. b. c. d. 3. Which of the following are reasons why the value of AHson for a gas such as CO2, dissolving in water, is negative? a. b. c. d. e. When a gas dissolves in a liquid, there is no endothermic step as with the lattice energy of a solid. When a gas dissolves in a liquid, there is only an exothermic step as with the lattice energy of a solid. The only enthalpy change is the one associated with hydration, and this is always positive. The only enthalpy change is the one associated with hydration, and this is always negative. When a gas dissolves in a liquid the lattice energy is always higher than the hydration energy, making the net enthalpy always negative.
