Question

Describe the enthalpy changes during the dissolving of NaCl into CH4:

A. The enthalpy of separating the solute is highly endothermic; the enthalpy of separating the solvent is slightly endothermic; the enthalpy of mixing is slightly exothermic; the enthalpy of solution is highly endothermic. B. The enthalpy of separating the solute is slightly endothermic; the enthalpy of separating the solvent is highly endothermic; the enthalpy of mixing is slightly exothermic; the enthalpy of solution is highly endothermic. C. The enthalpy of separating the solute is highly endothermic; the enthalpy of separating the solvent is slightly endothermic; the enthalpy of mixing is highly exothermic; the enthalpy of solution is slightly endothermic. D. The enthalpy of separating the solute is slightly endothermic; the enthalpy of separating the solvent is slightly endothermic; the enthalpy of mixing is highly exothermic; the enthalpy of solution is highly exothermic.

Explanation / Answer

The enthalpy of separating the solute is highly endothermic; the enthalpy of separating the solvent is slightly endothermic; the enthalpy of mixing is slightly exothermic; the enthalpy of solution is highly endothermic because NaCl has ionic bond which is strongest hence when it is broken alot of heat is released so highly endothermic whereas ch4 is non polar bonding so slightly endothermic not much heat is released whereas the solution gives out lot of heat so highly endothermic
