1. A house needs 200,000 Btu per day so that its temperature remanins at 68oF. How much CaCl26H2O(s) needs to be used to save enough energy for one day use? The process contains the heating of CaCl26H2O(s) from 68oF to 86oF and the reaction CaCl26H2O(s) = CaCl22H2O(s) + 4H2O(g). The water from the dehydration evaporates during the process. CaCl26H2O(s): ΔHof=-2607.89kJ/gmol, Cp=1.34J/g(oC) CaCl22H2O(s): ΔHof=-1402.90kJ/gmol, Cp=0.97J/g(oC)

* The standard reaction enthalpy for the hydrogenation of propene is -124 KJ/mole. The standard reaction enthalpy for the combustion of propane is -2220 KJ/mole. What is the standard enthalpy of combustion (in KJ/mole) of propene given that the enthalpy of formation for liquid water is -285.5 KJ/mole? NOTE: Express answer in the NEAREST WHOLE NUMBER.

Direct dehydrogenation of ethylbenzene to styrene is carried out in the vapor phase with steam over a catalyst consisting primarily of iron oxide. The reaction is endothermic, and can be accomplished either adiabatically or isothermally. Both methods are used in practice. The major reaction is the reversible, endothermic conversion of ethylbenzene to styrene and hydrogen: C6H3CH₂CH CoHsCHCH₂ + H₂ AH= 124.9 kJ/mol Competing thermal reactions degrade ethylbenzene to benzene C6H3CH₂CH3C6H6+ C₂H4 AH 101.8 kJ/mol Styrene also reacts catalytically to toluene: CH3CH₂CH3 + H2 CH3CH3 + CH4 AH=64.5 kJ/mol The reactions take place at 620°C. The costs are as shown in Table 1. The production rate of styrene is 200 mol/h. Chemical name Formula Cost (S/kmol) Ethylbenzene C6H5CH₂CH3 57.1 Styrene C.HSCHCH₂ 75.9 Benzene C6H6 32.8 Toluene C6H5CH3 25.8 Hydrogen H₂ 1.2 (as fuel) Methane CH4 4.0 (as fuel) Ethylene C₂H4 6.7 (as fuel) Correlation for the product selectivity and distribution are given as…
