Which of the following statements is correct concerning the below reactions?
(i) \(\rm ^1_0n+^{235}_{92}U\rightarrow^{236}_{92}U\rightarrow^{133}_{51}Sb+^{99}_{41}Nb+4^1_0n+Q\)
(ii) \(\rm ^1_0n+^{235}_{92}U \rightarrow ^{140}_{54}Xe+^{94}_{38}Sr+2^1_0n+Q\)
1
Both reactions (i) and (ii) are nuclear fusion reactions and during the reaction, they emit p particles in succession to achieve stable end products.
2
The reaction (ii) is a nuclear fission reaction but (i) is not and during the reaction, ∼ 50 MeV energy is released.
3
The reaction (i) is a nuclear fission reaction but (ii) is not and during the reaction, ∼ 216 MeV energy is released.
4
Both reactions (i) and (ii) are nuclear fission reactions and during the reaction, ∼ 216 MeV energy is released.
