What is the Ho of the equation 2C6H6(I)+15O2(g)12CO2(g)+6H2O(g) ? Given: HfoC6H6 =49.00kJ/mol,HfoCO2=394kJ/mol,HfoH2O=242kJ/mol. A. Ho=6,082kJ B. Ho=6,278kJ C. Hfo=6,082kJ D. Hfo=6,278kJ E. Hfo=6,278kJ Solution Ho=npHfo (products) nrHfo (reactants) Hfo(O2)=0 Ho=[6Hfo(H2O)+12Hfo(CO2)][2Hfo(C6H6)+15Hfo(O2)]= =[6(242)+12(394)][249+150]=6278(kJ) Answer: B. Ho=6,278kJ
