Hello Student
Please find your answer
This is due to the fact that while going down in a group a periodic table the electro positivity of elements increases as a result the bond between Na2CO3 is more strong than Li2CO3 . Li2Co3 is decomposed at a lower temperature since it requires less energy to break its bond as compared to Na2CO3.
