Delta H and heats of formation
44. When one mole of ethylene gas, C2H4, is burned in oxygen and hydrogen chloride, the products are liquid eth- ylene chloride, C2HaCh, and liquid water, 318.7 kJ of heat is evolved a. Write a thermochemical equation for the reaction. b. Using Table 8.3, calculate the standard heat of for- mation of ethylene chloride. +0.109 0.123 109 -31.6 No40 -109 C0 Na(z) 0.2057 0.1549 0.1338 -167.2 -334 a() -112 CiOs () 0.1400 -4112 +1644 850 Cr) +0.1161 0.1113 00 Ni() SL& NOCO -1139.7 +0.0086 0.1237 +01121 +0 1025 BaCO() Ba000 12163 7L.3 +0.1644 “3007 -409.1 P4() PC 0.1322 +0.1522 13623CuO) +0.1510 +0.1330 121.4 -3949F) +0.0057 +02164 0.2017 +0.1862 00 P(a CHCbl) -1345 -466 8 -0.138 91.8 PbCl) 217.1Fe) +0.2195 0 2395 S(o) -1170.7 ) -1118.4 -1372 Ha so.
