Why is `Li_(2)Co_(3)` decomposed at a lower temperature whereas `Na_(2)CO_(3)` at higher temperature:

Text Solution

Verified by Experts

`Li_(2)CO_(3)`, is a covalent compound, whereas `Na_(2)CO_(3)`, is an ionic compound. Therefore, lattice energy of `Na_(2)CO_(3)` is higher than that of `Li_(2) CO_(3)`. Thus, `Li_(2)CO_(3)`, is decomposed at a lower temperature.
