Use the equations for particle in a box to apply the free-electron model to hexatriene. If the length of hexatriene can be estimated to be 867 pm, determine the energy for first electronic transition in the molecule. Remember hexatriene has 6 TT electrons. b) What is the average position, , for the electron in the highest energy state after the excitation? You must show your work and justify your answer mathematically.

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)
