Question

when 2.3 g of sodium is ionized, 49.4 kJof heat is required, what is enthalpy of ionization of sodium?

​

Answer 1

Answer:

Explanation:

Ionisation energy: The Minimum energy required to remove most loosely held outer most shell electron in the ground state from an isolated gaseous atom is known as ionization potential.

Here,

No. of moles of sodium =  

(2.3×10^ −3 )/23 = 0.1×10  

−3

 mole

So energy needed to convert into ions = (495×10^3) (0.1×10^−3 )=49.5 joule
