The correct Answer is:
To solve the given question, we need to analyze both statements carefully and determine their validity. ### Step-by-Step Solution: 1. **Understanding Statement 1 (Assertion)**: - The statement claims that the disintegration of tritium (denoted as \( _{1}^{3}H \)) is accompanied by beta emission. - Tritium undergoes beta decay, where it transforms into helium-3 (\( _{2}^{3}He \)) and emits a beta particle (an electron, \( e^- \)). - The reaction can be represented as: \[ _{1}^{3}H \rightarrow _{2}^{3}He + e^- + \bar{\nu} \] - Therefore, Statement 1 is **true**. 2. **Understanding Statement 2 (Reason)**: - The statement indicates that tritium has a high neutron-to-proton (n/p) ratio. - Tritium has 2 neutrons and 1 proton, giving it an n/p ratio of: \[ n/p = \frac{2}{1} = 2 \] - Since the n/p ratio is greater than 1, it is indeed considered high. - Therefore, Statement 2 is also **true**. 3. **Relationship Between the Statements**: - Statement 2 provides a reason for Statement 1. A high n/p ratio in unstable nuclei often leads to beta decay as a mode of disintegration. - In this case, the high n/p ratio of tritium (2) contributes to its tendency to undergo beta decay. 4. **Conclusion**: - Both statements are correct, and Statement 2 accurately explains Statement 1. - Thus, the correct answer is that both statements are true, and Statement 2 is the reason for Statement 1. ### Final Answer: Both Statement 1 and Statement 2 are true, and Statement 2 is the correct reason for Statement 1.
