Enantiomers may possess different rates of reactions with other optically active compounds.

Explanation

### Step-by-Step Solution:

1. **Understanding Enantiomers**:
- Enantiomers are a pair of molecules that are non-superimposable mirror images of each other. They have the same molecular formula and connectivity but differ in spatial arrangement.

2. **Identical Properties**:
- Enantiomers possess identical chemical and physical properties in an achiral environment. This means that in a non-chiral medium, they will behave the same way in terms of melting point, boiling point, and density.
