Ethyl chloride (C2H5Cl), a substance used as a topical anesthetic, is prepared by reaction of ethylene with hydrogen chloride: C2H4(g)+HCl(g)C2H5Cl(g)H=72.3kJ. (Figure 1) Figure 1 of 1 How much PV work is done (in kilojoules), if 90.0g of ethylene and 120g of HCl are allowed to react at atmospheric pressure and the volume change is 71.9L ? Request Answer Part B What is the value of E (in kilojoules) for the reaction
