Question 3
Step by step
Solved in 2 steps
- 2. (a) The heat of combustion of liquid benzaldehyde (C6H5CHO) is -3393 kJ/mole, and that of liquid 2,4,6-cycloheptatrien-1-one (C₂H6O) is -3470 kJ/mole. Assume that both combustions result in products, CO2 and H₂O, that are entirely in the gas phase. Using the standard chemical equation for the combustion of a hydrocarbon, find the heats of formation (in kJ/mol) for both benzaldehyde and 2,4,6-cycloheptatrien-1-one in the liquid phase. (b) Consider the isomerization from 2,4,6-cycloheptatrien-1-one to benzaldehyde. What is the enthalpy change (in kJ/mol) for this reaction? Is it endothermic or exothermic? (c) If ArxnS = -18 J/mol-K for the isomerization reaction, find ArxnG at 350 K (in kJ/mol) and determine if it is spontaneous in the liquid phase at this temperature. For this calculation, you may assume that ArxnH and ArxnS are constant between 300 and 350 K.4 – Use bond-dissociation enthalpies (pg 167 of text) to calculate the DHo for each of the following reactions. CH3CH2CH3 + H2 g CH3CH3 + CH4 CH3CH2Cl + HI g CH3CH2I + HClComment on the difference between the enthalpy of combustion values of anthracene, napthalene, and phenathrene. delta H anthracene = -7063.8±5.3 kJ/mol delta H napthalene = -5160. ± 20. kJ/mol delta H phenanthrene is -7040. ± 30. kJ/mol

It needs to be correct. Show complete solutions and how the total enthalpy and total entropy are obtained. Answer must be correct. Calculate the ΔG° of the reaction below at 785 K. Is the reaction spontaneous or not? (Note: ΔH° and ΔS° are constant with respect to temperature.)
