Thermochemistry: Gibbs Free Energy

Very Hard

(Originais Teachy 2023) - Question Very Hard of Chemistry

Consider the formation reaction of carbon monoxide (CO) from the elements carbon (C) and oxygen (O2), represented by the thermochemical equation: C(s) + 1/2O2(g) -> CO(g). The standard enthalpy of formation of CO is -110.5 kJ/mol. Using concepts of thermodynamics and stoichiometry, determine the Gibbs free energy (G) for the formation of 1 mol of CO(g) at a temperature of 298 K and pressure of 1 atm. Consider that the standard entropy of reaction of CO is -198.3 J/(mol*K) and that the standard enthalpy of formation of C(s) is 0 kJ/mol. Disregard volume changes during the reaction and consider gases as ideal.

A pharmaceutical company is rolling out a new range of medications based on various organic compounds. To ensure that these products are effective and consistent, chemists need to sort these compounds into the right organic series, taking into account different structures of carbon chains and the functions involved. Given this backdrop, what criteria should be used to accurately determine if the compounds fall under a homologous, isologous, or heterologous series?

In a plastics factory, the chemists need to identify different planar isomers of a compound used in the production of polymers. Understanding the properties of isomers, they aim to classify the type of isomerism present and figure out the number of possible isomers for a specific compound. So, how many planar isomers are there for 2-butene?
