A chemical company is setting up a plant to manufacture the compound called Chloroethane, C2H5Cl. Their chemist can make it in two ways, either from ethene (reaction 1) or ethanol (reaction 2_Reaction 1: C2H4 + HCL ---> C2H5ClReaction 2: C2H5OH+ HCL ---> C2H5Cl + H2O
Calculate the percentage atom economy of reaction 2 (2 marks)
