Answer 2

Energy required to dissociate 4g of gaseous hydrogen into free gaseous atoms is 208 Kcal at 25  

The reaction involved is,

H  

2

​  

(g)→2H(g)                

 ΔH=H-H bond energy

Since, moles =  

molecular mass of compound

mass of compound

​  

 

So, moles of H  

2

​  

=  

2

4

​  

=2

Hence, energy required to break 4gm or 2 moles of H  

2

​  

 into gaseous atoms = 208Kcal=2×H-H bond energy

H-H bond energy = 104Kcal
