Why is Li 2 CO 3 decomposed at a lower temperature whereas Na 2 CO 3 at a higher temperature?

Options

  1. ALi 2 CO 3 has a stronger chemical bond than Na 2 CO 3 , making it more stable at lower temperatures.
  2. BLi 2 CO 3 has a weaker chemical bond than Na 2 CO 3 , making it less stable at higher temperatures.
  3. CThe atomic radius of lithium is smaller than sodium, allowing for stronger bonds in Li 2 CO 3 .
  4. DThe atomic radius of lithium is larger than sodium, allowing for stronger bonds in Li 2 CO 3 .

Correct answer

C. The atomic radius of lithium is smaller than sodium, allowing for stronger bonds in Li 2 CO 3 .

Step-by-step solution

Correct Option is : (C) The atomic radius of lithium is smaller than sodium, allowing for stronger bonds in Li 2 CO 3 .
