1. When solid benzene (molecular weight 78.11 g mol-1) melts to form liquid benzene its density changes from 0.891 g cm-3 to 0.879 g cm-3. The melting temperature of benzene at 1.00 atm of pressure is 278.7 K. Its enthalpy of melting is 10.59 kJ mol-1. Estimate the melting point of benzene at 1000 atm. Assume the density and enthalpy of fusion of benzene are independent of pressure. Helpful hint : 1 L atm = 101.3 J 2. Consider the gas phase dimerization of butadiene to form vinylcylo …
