The general form of potential energy cur...

The general form of potential energy curve for atoms or molecules can be represented by the following equation `U(R)= (A)/(R^(n))- (B)/(R^(m))`. Here, R is the interatomic or molecular distance, A and B are coefficients, n and m are the exponents. In the above equation

A

First term represents the attractive part of the potential

B

Second term represents the attractive part of the potential

C

Both terms represents the attractive part of the potential

D

Second term represents the repulsive part of the potential

Text Solution

Verified by Experts

The correct Answer is:
B
`U(R)= (A)/(R^(n))-(B)/(R^(m))`
For attractive force, `U rarr` -ve
For repulsive force `U rarr` + ve
