Question

What is the value of electron gain enthalpy of k + if the IE1 of k is 4.3 electron volt???

Answer 1

Answer:-4.3ev

Explanation:

The ionization enthalpy of an element is equal to the electron gain enthalpy of unipositive Ion (but sign is different)

Answer 2

$\huge\underline\purple{\sf Answer}$

➡The value is - 4.3 .

➡As both are having opposite signs.

➡We can say that the Ionisation energy is equal to the Electron gain enthalpy.

➡But the signs vary for the both.

➡If IE is positive Electron gain enthalpy Is negative.

➡ IE = - EA.
