The curve in the diagram shows a potential energy U of two molecules for different values of intermolecular separation r. Which part of the curve represent that the intermolecular force is (i) repulsive, (ii) attractive ?

Text Solution

AI Generated Solution

To determine which part of the potential energy curve represents repulsive and attractive intermolecular forces, we can follow these steps: ### Step 1: Understand the Relationship Between Potential Energy and Force The force \( F \) between two molecules can be derived from the potential energy \( U \) using the formula: \[ F = -\frac{dU}{dr} \] This means that the force is related to the slope of the potential energy curve. ...
