Suppose a pair of chemical compounds A and B can react in two different ways: A+B C Reaction 1 gives product C. A+BD Reaction 2 gives product D. The following facts are known about the two reactions: . Both reactions are exothermic, but the heat of reaction of Reaction #1 is larger. • If a reaction vessel is charged ("filled") with A and B, then at first D is produced faster than C. Use these facts to sketch a qualitative reaction energy diagram for both reactions. Note: because these sketches are only qualitative, the energies don't have to be exact. They only have to have the right relationship to each other. For example, if one energy is less than another, that fact should be clear in your sketch. energy A+B Reaction 1. energy A+B Reaction 2 olo Ar E DEATH OF A BACHELOR

A student dissolves 11.9 g of ammonium nitrate (NH4NO3) in 200. g of water in a well-insulated open cup. He then observes the temperature of the water fall from 22.0 °C to 16.5 °C over the course of 7.6 minutes. Use this data, and any information you need from the ALEKS Data resource, to answer the questions below about this reaction: NH4NO3 (s) NH(aq) + NO3 (aq) You can make any reasonable assumptions about the physical properties of the solution. Be sure answers you calculate using measured data are rounded to 2 significant digits. Note for advanced students: it's possible the student did not do the experiment carefully, and the values you calculate may not be the same as the known and published values for this reaction. Is this reaction exothermic, endothermic, or neither? If you said the reaction was exothermic or endothermic, calculate the amount of heat that was released or absorbed by the reaction in this case.

We can use Hess's Law (and some creativity!) to learn about the energetics of reactions that occur in remote environments. Consider the atmospheric reaction, NO + O → NO2 (a) Use the dissociation energy of O2, 498.34 kJ/mol, and the standard heats of formation for NO (+90.25 kJ/mol) and NO2 (+33.18 kJ/mol) to derive the enthalpy change for this reaction.
