- Explain the decomposition of nitroglycerin in terms of relative bond enthalpies.arrow_forwardA particular chemical reaction has AH° = +250 kJ/mol. Which of the following statements are true concerning this reaction? Choose all that apply Heat moves from the system to the surroundings The reaction is endothermic Overall bond length has increased in the products The molecules in the system will slow down as the kinetic energy is converted to potential energy O The enthalpy of the products is lower than the enthalpy of the reactantsarrow_forwardIn an ionic compound, the size of the ions affects the internuclear distance (the distance between the centers of adjacent ions), which affects lattice energy (a measure of the attractive force holding those ions together). Based on ion sizes, arrange these compounds by their expected lattice energy. Note that many sources define lattice energies as negative values. Please arrange by magnitude and ignore the sign. |lattice energy| = absolute value of the lattice energy CSF Greatest lattice energy (strongest bonds) Least lattice energy (weakest bonds) CsBr Answer Bank CsCl CSIarrow_forward
