In an exothermic reaction, the enthalpy change is negative. which of the following is also true for an exothermic reaction?

the products have a lower potential energy than the reactants.

the reactants have a lower potential energy than the products.

the potential energy of both the reactants and products is the same.

the potential energy decreases, and then increases sharply at the end of the reaction.

The table lists the lattice energies of some compounds.compoundlattice energy (kj/mol)lif            –1,036licl            –853naf            –923kf            –821nacl            –786which statement about crystal lattice energy is  best  supported by the information in the table? the lattice energy increases as cations get smaller, as shown by lif and kf.the lattice energy increases as the cations get larger, as shown by lif and licl.the lattice energy decreases as cations get smaller, as shown by nacl and naf.the lattice energy decreases as the cations get smaller, as shown by naf and kf.
