Estimate the change in enthalpy for the following reaction using bond energies: 2 H2 + O2 ---> 2 H2O
PCl5 is a white solid, which volatilises at 160oC and melts at 148oC under pressure. Molten PCl5 conducts an electric current readily. At 180oC PCl5 vapour has a density of 9.3 g/L corrected to the standard conditions. At 250oC a sample of PCl5 exerts a pressure, which is twice the expected value. Discuss these observations and
