The correct Answer is:
To solve the assertion and reason question, we will analyze both the assertion (A) and the reason (R) step by step.
### Step 1: Understand the Assertion (A)
The assertion states that "Some metals like platinum and palladium can be used as storage media for hydrogen."
- **Analysis**: This statement is true. Platinum (Pt) and palladium (Pd) are known for their ability to absorb and store hydrogen. They are often used in applications where hydrogen storage is necessary.
### Step 2: Understand the Reason (R)
The reason states that "Platinum and palladium can absorb large volumes of hydrogen."
- **Analysis**: This statement is also true. Both platinum and palladium can absorb significant amounts of hydrogen due to their ability to form interstitial hydrides. This means that hydrogen atoms can fit into the spaces (interstices) between the metal atoms in their crystal lattice.
### Step 3: Determine the Relationship Between A and R
Now we need to determine if the reason correctly explains the assertion.
- **Explanation**: Since the reason (R) correctly explains why the assertion (A) is true (i.e., the ability of platinum and palladium to absorb large volumes of hydrogen is the reason they can be used as storage media), we conclude that both the assertion and reason are correct, and the reason is a valid explanation of the assertion.
### Conclusion
Both the assertion and reason are correct, and the reason correctly explains the assertion. Therefore, the correct answer is that both statements are true and the reason is the correct explanation of the assertion.
### Final Answer
- **Assertion (A)**: True
- **Reason (R)**: True
- **Conclusion**: Both A and R are correct, and R is the correct explanation of A.
