(30/100). Consider the production of 1,1-dichloroethane (C2H4Cl2) from ethylene (C2H4) and chlorine (Cl2). Reaction is given bellow. This gas-phase reaction is the first step in producing polyvinyl chloride (PVC). The feed ratio of reactants is 2 moles chlorine: 1 mole ethylene. You may assume hrxno does not change with temperature. Calculate the maximum temperature at which 90% conversion can be obtained at a pressure of 1 bar. C2H4(g)+Cl2(g)C2H4Cl2(g)
