Question

ΔΗρο, value for chlorine is 37 eV The amount of energy released when 2g chlorine is comp (A) 24 kcal (B) 48 kcal (C) 7.4 kcal (D) 85 3 kcal​

Answer 1

Answer:

Energy realise – when one electron is added to neutral atom .

cl + e– = cl–

energy realise = 3.7 .

1 EV = 23.06 kcal

energy = 3.7 × 23.06 kcal

2gm

mole = weight / mole

2g =

35.5

3.7 × 23.06 kcal / mole × 2/35.5 mole

Hince , mole and mole katt do .kind your information .

48 kcal
