Chapter 4, Problem 47CTQ

For ${\text{NH}}_3$ (ammonia) and ${\text{H}}_2\text{O}$ (water)...
a. Use curved arrows to show the most likely acid-base reaction, and draw the resultingproducts. (Hint: First decide which is the stronger acid, and which is the stronger base.)
b. Mark each curved arrow with a positive (bond-breaking) or negative (bond-forming) numberindicating the energy change associated with that arrow (in $\text{p}{K}_a$ units).
c. Calculate $\Delta H_{rxn}$ and write this number above a set of reaction arrows that indicate whichdirection is downhill/favorable (in the example, the reaction is downhill to the right).
d. Sketch an energy diagram for the reaction.
e. Is your energy diagram consistent with the fact that, in this case, the most likely acid-basereaction is endothermic?
