Answer 1

Answer:

IP1 value of chlorine is 12ev and electron affinity of chlorine is 3.6 ev. Number of chlorine atoms in the gaseous state that can be ionised by utilising the energy that is liberated in the process. Tot involving one mole of chlorine atoms is [ ] a) 1.8 x 1023 b) 3. C)310 . 3. d) 1.8 x 10​

Explanation:

Answer 2

Given:

Ionisation Potential = 12$eV$

Electron Affinity = 3.6$eV$

To Find:

Number of chlorine atom in the gaseous state that can be ionised by utilising the energy that is liberated in the given process

Solution:

EA of chlorine is that energy which is release when we add electron to the chlorine atom

$Cl$+$e^{-}$→$Cl^{-}$

IE of chlorine is that energy which required to take out one electron from gaseous atom

$Cl$ →$Cl^{+} + e^{-}$

1 mole = 6.023 × $10^{23}$ $atom$

Energy released = Energy Absorbed

6.023 × $10^{23}$ $atom$ × 3.6 = 12 × n

n = 1.8 × $10^{23}$ $atom$
