Final answer:
The calculation of toluene production from methylcyclohexane requires additional stoichiometric data not provided. Analogous principles can be explained using methane combustion, relating moles of reactants or products to mass and volume for theoretical and percent yield calculations.
Step-by-step explanation:
The problem given requires information beyond the thermochemical data provided to calculate the conversion of methylcyclohexane (MCH) to toluene. The student is asked to calculate the barrel of toluene formed from one barrel of MCH under specific conditions. The reaction likely involves dehydrogenation of MCH to produce toluene, a process which requires knowledge of reaction stoichiometry and yields, which are not provided here. However, the principles for stoichiometric calculations and enthalpy changes can be explained using the combustion of methane as an analogy, where 1 mole of CH4 releases 890.4 kJ of energy. The method involves linking the moles of reactants or products to mass or volume to find the theoretical yield and then comparing to actual yield for percent yield calculations.
