Question

The interaction energy of London forces between two particles is proportional to r^x, where r is the distance between the particles. The value of x is ______.

Options

• 3

• −3

• −6

• 6

Answer 1

The interaction energy of London forces between two particles is proportional to r^x, where r is the distance between the particles. The value of x is −6.

Explanation:

For London dispersion forces,

E `∝ ->` r⁻⁶;

So, x = −6
