The potential energy(y) curve for `H_2` formation as a function of inrtnuclear distance(x) of the H atoms is shown below

The bond energy of `H_2` is :

A

`((c-a))/2`

B

`((b-a))/2`

C

`(c-a)`

D

`(b-a)`

Text Solution

Verified by Experts

The correct Answer is:
D
Potential energy of two H atoms at infinite distance = a Potential energy of two H atoms at distance equal to bond length = b
So, The bond energy of `H_2` = (b-a)
