Chapter 3, Problem 3A.2ST
Interpretation Introduction
Interpretation:
The increased temperature of the hot source has to be calculated to increase the efficiency of heat engine by
Concept Information:
Heat engine: combustion of fuel producing heat that is transferred and completely converted into work with maximum efficient. All heat engines have both ‘hot’ regions, the source and ‘cold’ region, the sink. Some energy is dispersed into the cold sink as heat and not used to do work.
Efficiency of heat engine:

A. Draw the structure of the strongest acid in the table above.
B. Explain why cyanoacetic acid and methoxyacetic acid are more acidic than their correspondingly
substituted benzoic acid counterparts.
Draw the curved arrow mechanism for this reaction starting with 2-propanol in sulfuric acid. Show all nonzero formal charges and all
nonbonded electrons in each step. Species not involved in a particular step do not need to be included in that step, and resonance forms
do not need to be shown. Note that the alcohol is in much higher concentration than H₂O in this reaction.
