"cold packs" used to treat sports injuries commonly consist of two compartments; water or some kind of gel on one side and solid ammonium nitrate, NH4NO3, on the other. The chemical equation corresponding to the dissociation reaction that occurs when you break the seal between the compartments is given below: NH4NO3(s)-->NH4+(aq)+NO3(aq) A. Given that the cold packs get colder, is the above reaction exo-,endo-, or isothermic? Provide the definition of the appropraite word and apply the concepts of system and surroundings to this particular situation. Be as concise as possible.

Consider a small open economy where workers care about their real consumption wage. Assume, in addition, that the Marshall-Lerner condition holds. This economy starts at the longrun equilibrium and suddenly experiences the following shock. Households get easier access to mortgages and, as a result, the savings rate falls in this economy. What will be the effect of this shock on the medium run equilibrium in this economy? Describe the changes in the equilibrium employment, RER, Trade Balance and real consumption wage. Draw the appropriate diagrams and briefly explain your reasoning. [Word limit = 250 words]
