Does higher lattice energy mean more stable?
Lattice energy is the energy required to break an ionic lattice into its constituents ions. So, higher the lattice energy, higher will be the energy required to break the ionic bond between the constituent ions in a crystal lattice. Therefore, higher will be the stability of the ionic compound.
Which of the following compound has the highest lattice energy?
Mg2+ ion has a smaller size when compared to Ca2+ ad thus MgO has the highest lattice energy among the given compounds.
Which compound possesses the highest lattice energy?
Answer: 1. Sodium fluoride (NaF) shows highest lattice energy among these compounds since Na+ features ions of the same charge, the lattice energy increases as the size of the ions increases.
Is lattice energy exothermic or endothermic?
In one definition, the lattice energy is the energy required to break apart an ionic solid and convert its component atoms into gaseous ions. This definition causes the value for the lattice energy to always be positive, since this will always be an endothermic reaction.
Is lattice energy directly proportional to stability?
Thermodynamics stability is directly proportional to the lattice energy. Lattice energy is directly proportional to the charge and inversely proportional to the size.
What does difference in lattice energy mean?
Lattice energy: The difference in energy between the expected experimental value for the energy of the ionic solid and the actual value observed. More specifically, this is the energy gap between the energy of the separate gaseous ions and the energy of the ionic solid. It has ions with the largest charge.
How do lattice energy compare to ionic compounds?
Lattice enthalpy of two salts can be compared by using Born–Lande equation (one of method) as, So, greater the charges of cation & anion, higher will be the lattice energy of the corresponding salt. Again, smaller the ionic radii of cation and anion, higher will be the lattice energy.
