How to determine exothermic lattice energy
Web2 days ago · Give a specific example of a compound that should have a high lattice energy, and explain why its lattice energy is high. arrow_forward Compare your answers from parts a and b of Exercise 69 with H values calculated for each reaction using standard enthalpies of formation in Appendix 4. WebThe increased temperature means that the reaction released energy. Endothermic reactions get cold. Exothermic reactions get hot. The reaction would be probably be exothermic since it involves precipitation of AgBr from the solution. (Edit: and also because the temperature of the reaction mixture is increasing) Here the energetics merely don't ...
