Pressing the 'Show Answer' button will cause the correct answer to display and you will no longert be able to submit an anser for that question.Nonetheless, the only way to get the 'correct answer' is to do a proper Born-Haber analysis of the data provided.

In most cases, the change is less than 1%. To remove the possibility of your 'answering' the questions by merely looking in a reference book, the thermodynamic values the page presents have been very slightly altered from the literature values.The page creates and calculates the lattice energy fresh each time.(ii) Use your BornHaber cycle and the standard enthalpy data given below to calculate a value for the electron affinity of chlorine. Include state symbols for all species involved. The data is presented in such a fashion that all answers calculated should be integers and should be negative. (a) (i) Draw a fully-labelled BornHaber cycle for the formation of solid barium chloride, BaCl 2, from its elements. Be very careful with your calculations.There are a number of very important rules: Regardless, determine the value of the missing heat, enter it and press 'Check Answer'. Most of the time, the missing heat will be the lattice energy, but, occasionally, it will be another term. When you press 'New Problem', a window will open with a set of thermochemical data related to an ionic compound. This page provides exercises in the use of the Born-Haber cycle to determine lattice energies of ionic compounds.
