D. Statement 1 is false, statement 2 is true

Explanation

To analyze the given statements regarding the bond strength of D-Cl versus H-Cl and the reactivity of chlorine with H2 versus D2, we can break down the reasoning step by step.

### Step 1: Understanding Bond Strength
- **Bond Strength Comparison**: The bond strength between two atoms can be influenced by the masses of the atoms involved. In this case, we are comparing the D-Cl bond with the H-Cl bond.
- **Isotopes**: Deuterium (D) is an isotope of hydrogen (H) with one neutron, making it heavier than hydrogen. The heavier the atom in a bond, the stronger the bond tends to be due to reduced vibrational amplitude.

### Step 2: Analyzing Statement 1
- **Statement 1**: "D-Cl bond is stronger than H-Cl bond."
- **Conclusion**: This statement is generally considered **true** because the D-Cl bond is stronger than the H-Cl bond due to the reduced vibrational amplitude of the heavier deuterium atom.

### Step 3: Understanding Reactivity
- **Reactivity Comparison**: The reactivity of a molecule often depends on the bond strength. Weaker bonds tend to break more easily, leading to higher reactivity.
- **Chlorine Reaction**: Chlorine reacts with hydrogen (H2) and deuterium (D2). Since H-Cl bonds are weaker than D-Cl bonds, H2 will react more readily with chlorine than D2.

### Step 4: Analyzing Statement 2
- **Statement 2**: "Chlorine reacts more rapidly with H2 than with D2."
- **Conclusion**: This statement is also **true** because the H-Cl bond is weaker than the D-Cl bond, making H2 more reactive with chlorine.

### Final Conclusion
- Both statements are true:
- Statement 1 is true: D-Cl bond is stronger than H-Cl bond.
- Statement 2 is true: Chlorine reacts more rapidly with H2 than with D2.
