Final answer:
To find the enthalpy at the compressor exit, one would typically consider the gas properties and work done on the gas. However, the provided solution steps involve using Hess's law to find the change in enthalpy for a chemical reaction by summing individual enthalpy changes of related reactions.
Step-by-step explanation:
To find the enthalpy at the compressor exit in a thermodynamic cycle, we might need to look at the properties of the gas before and after the compression, as well as the work done on the gas. However, the solution provided goes into the details of finding the change in enthalpy for a chemical reaction using Hess's law. For this, we consider the balanced chemical equations and use the standard enthalpies of formation.
Hess's law indicates that the total enthalpy change for a reaction is the sum of the enthalpy changes for individual steps that lead to the final reaction. By reversing, multiplying, and summing appropriate reactions and their respective enthalpy changes, we can find the total enthalpy change for the desired reaction.
