Question

In a fission reaction, ${ }_{92}^{236} U \rightarrow{ }^{117} X+{ }^{117} Y+n+n$ the binding energy per nucleon of $X$ and $Y$ is 8.5 MeV whereas of ${ }^{236} U$ is 7.6 MeV . The total energy liberated will be about

Professor PC Thomas Classes · Answer

Energy liberated = Total BE of products - Total BE of reactants = $(234 	imes 8.5) - (236 	imes 7.6) \approx 1989 - 1793.6 = 195.4 \approx 200$ MeV.
