Options

A. (A)
B. (B)
C. (C )
D. (D)

Answer

To analyze the given statements, we will break down the concepts involved in bimolecular reactions and the role of collisions in chemical kinetics.

### Step-by-Step Solution:

1. **Understanding Bimolecular Reactions**:
- A bimolecular reaction involves two reactant molecules that collide to form products. This means that for a reaction to occur, the reactants must come into contact with each other.

**Hint**: Recall that bimolecular reactions specifically involve two reactant molecules interacting.

2. **Collision Requirement**:
- According to collision theory, for a reaction to take place, reactant molecules must collide with sufficient energy and the correct orientation. This is essential for the breaking of existing bonds and the formation of new ones.

**Hint**: Think about the conditions necessary for effective collisions in chemical reactions.

3. **Bond Breaking and Formation**:
- During the collision of reactant molecules, bonds between atoms can break, and new bonds can form. This process is crucial for the transformation of reactants into products.

**Hint**: Consider how the rearrangement of atoms during a collision leads to the formation of new substances.

4. **Evaluating Statement 1**:
- Statement 1 asserts that for a bimolecular reaction to occur, the reactants must collide. This is true, as collisions are a prerequisite for any reaction to take place.

**Hint**: Reflect on the definition of bimolecular reactions and the necessity of molecular interactions.

5. **Evaluating Statement 2**:
- Statement 2 claims that bond breaking and formation occur during the collision. This is also true, as the collision leads to the rearrangement of atoms, resulting in the breaking of old bonds and the formation of new ones.

**Hint**: Think about the role of energy in breaking bonds and how this relates to the concept of activation energy.

6. **Conclusion**:
- Both statements are correct. Furthermore, Statement 2 serves as an explanation for Statement 1, as it describes the process that occurs during the collisions mentioned in Statement 1.

**Hint**: Consider how one statement can provide a rationale for the other in the context of chemical reactions.

### Final Answer:
- Both Statement 1 and Statement 2 are true, and Statement 2 is the correct explanation for Statement 1.
