Final answer:
The maximum allowable pressure of the air leaving the compressor should be determined based on safety limits and operational ranges that do not compromise system integrity or yield, guided by Le Chatelier's principle for exothermic reactions.
Step-by-step explanation:
Using sensitivity analysis to determine the maximum allowable pressure of air leaving the compressor involves assessing how the output of the system, in this case, the production of propanol, might change in response to variations in the pressure and temperature conditions. While actual calculations are not provided in the question, some general suggestions for maximizing yield at equilibrium can be proposed. It is known that for an exothermic reaction, increasing the pressure and decreasing the temperature can potentially lead to a higher yield of the desired product according to Le Chatelier's principle. However, these conditions must be balanced with the practical limitations of the equipment and safety considerations. Therefore, the pressure should not exceed the safety limits of the compressor and associated machinery, and temperatures should remain within operational ranges that do not compromise the integrity of the system or lead to unintended side reactions.
