E) condensation has occurred The solvent plays an important role in the dissociation process. An exothermic process has a negative value of enthalpy, whereas a positive value of enthalpy relates to an endothermic process. Cloudflare Ray ID: 5eda3ea6ef4e1e47 Consider the following information for a... 1. Becsause in solution the ions come apart and become mobile and thus able to transport electrons whereas in the solid, the ions asre … In order to account for a solid dissolving in a liquid, we have to consider the enthalpy of lattice dissociation, which is the energy required for one mole of solid to dissociate into its gaseous ions, and the enthalpy of hydration, the energy required for one mole of gaseous ions to produce dissolved ions in an aqueous solution. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. B) sublimation has ocurred. a) When something becomes colder, we usually say the reaction is endothermic. Does ammonium chloride conduct electricity? Relevance. C) ammonia gas is evolved. A) the solution is unsaturated. Lv 5. NH4Cl + H2O + heat -> products. Save my name, email, and website in this browser for the next time I comment. The liquid has to provide energy to the molecules making the whole process as an endothermic reaction. What drives the process? Create your account.
