Sodium and potassium react with water mu...

Sodium and potassium react with water much more vigorously than lithium because:

A

sodium and potassium have high values of hydration energy as compared to that of lithium.

B

sodium and potassium have higher melting point than that of lithium.

C

sodium and potassium have lower melting point than that of lithium.

D

sodium and potassium have lower hydration energy htan that of lithium.

Text Solution

Verified by Experts

The correct Answer is:
3
When sodium and potassium react with water, the heat evolved causes them to meld, giving a larger area of contact with water, lithium on the other hand, does not melt under these condition and thus reacts more slowly.
Melting point `(.^(@)C)` `{:(Li,Na,Na,),(180,98,64,):}`
