Trichloroethylene, a widely used degreasing solvent for machine parts, is produced in a two-step reaction sequence. ethylene is first chlorinated to yield tetrachloroethane (rxn i), which is dehydrochlorinated to form trichloroethylene (rxn ii): rxn i: latex: c_2h_4\left(g\right)+2cl_2\left(g\r ight)\: \rightarrow\: c_2h_2cl_4\left(l\right)+h_2\left(g \right) c 2 h 4 ( g ) + 2 c l 2 ( g ) → c 2 h 2 c l 4 ( l ) + h 2 ( g ) latex: \bigtriangleup h^\circ_r=-385.76\: kj â–ł h r â = â’ 385.76 k j rxn ii: latex: c_2h_2cl_4\left(l\right)\: \rightarrow\: c_2hcl_3\left(l\right)+hcl\left(g\r ight) c 2 h 2 c l 4 ( l ) → c 2 h c l 3 ( l ) + h c l ( g ) the standard heat of formation of liquid trichloroethylene is -276.2 kj/mol. use hess's law to calculate the standard heat of the net reaction: latex: c_2h_4(g) + 2cl_2(g) \rightarrow c_2hcl_3(l) + h_2(g) + hcl(g) c 2 h 4 ( g ) + 2 c l 2 ( g ) → c 2 h c l 3 ( l ) + h 2 ( g ) + h c l ( g ) if 307 mol/h of c2hcl3(l) is produced in the net reaction and the reactants and products are all at 25oc and 1 atm, how much heat is evolved in the process (kw)? (assume latex: \dot{q} = \delta\dot{h} q ë™ = î” h ë™ )
