Textbook Question
Chapter 6, Problem 6.29P
An air conditioner is designed to bring 10.000 ft3/min of outside air (90°F, 29.8 inches Hg, 88% relative humidity) to 40°F, thereby condensing a portion of the water vapor, and then to reheat the air before releasing it into a room at 65°F. Calculate the rate of condensation (gallons H2O/min) and the volumetric flow rate of the air delivered to the room. (Suggestion: On the flowchart, treat the cooling— condensation and the rehearing as separate process steps.)

- The SN 1 mechanism starts with the rate-determining step which is the dissociation of the alkyl halide into a carbocation and a halide ion. The next step is the rapid reaction of the carbocation intermediate with the nucleophile; this step completes the nucleophilic substitution stage. The step that follows the nucleophilic substitution is a fast acid-base reaction. The nucleophile now acts as a base to remove the proton from the oxonium ion from the previous step, to give the observed product. Draw a curved arrow mechanism for the reaction, adding steps as necessary. Be sure to include all nonzero formal charges.
