An overhead vapor stream from the distillation column is to be condensed under atmospheric conditions and, while part of it is returned to the column as reflux, the remaining part is withdrawn as product. If the vapor consists of 16mol% water and 84%n-propanol, estimate the maximum operating temperature of the condenser. The binary mixture of water (1) and n-propanol (2) is represented by the NRTL equation with the following parameters: g12g22=9218.80J/molg21g11=414.77J/mol=0.3
