Match the List-I with List-II. List-I A. ¹₀n + ²³⁵₉₂U → ¹⁴⁰₅₄Xe + ⁹⁴₃₈Sr + 2¹₀n B. 2H₂ + O₂ → 2H₂O C. ²₁H + ³₁H → ⁴₂He + ¹₀n D. ¹₁H + ³₁H → ²₁H + ²₁H List-II I. Chemical reaction II. Fusion with +ve Q value III. Fission IV. Fusion with −ve Q value Choose the correct answer from the options given below: (1) A-III, B-I, C-IV, D-II (2) A-II, B-I, C-IV, D-III (3) A-III, B-I, C-II, D-IV (4) A-I, B-I, C-III, D-IV
- (1) A-III, B-I, C-IV, D-II
- (2) A-II, B-I, C-IV, D-III
- (3) A-III, B-I, C-II, D-IV
- (4) A-I, B-I, C-III, D-IV
Correct answer: (3) A-III, B-I, C-II, D-IV
Solution
Option (3) correctly identifies the processes: A is a fission reaction where a heavy nucleus splits, B is a chemical reaction forming water, C is a fusion reaction with a positive Q value as it releases energy, and D is a fusion reaction with a negative Q value as it requires energy input.
