The correct Answer is:
To calculate the ground state Q value of the induced fission reaction given by the equation: \[ n + _{92}^{235}U \rightarrow _{92}^{236}U \rightarrow _{40}^{99}Zr + _{52}^{134}Te + 2n \] we will follow these steps: ### Step 1: Understand the Q value formula The Q value of a nuclear reaction is given by the equation: \[ Q = \Delta m \cdot c^2 \] where \(\Delta m\) is the change in mass during the reaction, and \(c\) is the speed of light. We can also express it in terms of energy: \[ Q = \Delta m \cdot 931.2 \text{ MeV} \] ### Step 2: Identify the masses involved in the reaction From the problem, we have the following masses: - Mass of neutron, \(m(n) = 1.0087 \, \text{amu}\) - Mass of Uranium-235, \(M(^{235}U) = 235.0439 \, \text{amu}\) - Mass of Zirconium-99, \(M(^{99}Zr) = 98.916 \, \text{amu}\) - Mass of Tellurium-134, \(M(^{134}Te) = 133.9115 \, \text{amu}\) ### Step 3: Calculate the total mass before and after the reaction **Before the reaction:** - Total mass before = Mass of \(^{235}U\) + Mass of neutron \[ \text{Total mass before} = M(^{235}U) + m(n) = 235.0439 + 1.0087 \] **After the reaction:** - Total mass after = Mass of \(^{99}Zr\) + Mass of \(^{134}Te\) + 2 * Mass of neutron \[ \text{Total mass after} = M(^{99}Zr) + M(^{134}Te) + 2 \cdot m(n) \] \[ = 98.916 + 133.9115 + 2 \cdot 1.0087 \] ### Step 4: Calculate the change in mass (\(\Delta m\)) Now, we can calculate \(\Delta m\): \[ \Delta m = \text{Total mass before} - \text{Total mass after} \] ### Step 5: Substitute the values and calculate \(\Delta m\) 1. Calculate Total mass before: \[ \text{Total mass before} = 235.0439 + 1.0087 = 236.0526 \, \text{amu} \] 2. Calculate Total mass after: \[ \text{Total mass after} = 98.916 + 133.9115 + 2 \cdot 1.0087 = 98.916 + 133.9115 + 2.0174 = 234.8459 \, \text{amu} \] 3. Now calculate \(\Delta m\): \[ \Delta m = 236.0526 - 234.8459 = 1.2067 \, \text{amu} \] ### Step 6: Calculate the Q value Now we can substitute \(\Delta m\) into the Q value formula: \[ Q = \Delta m \cdot 931.2 \, \text{MeV} \] \[ Q = 1.2067 \cdot 931.2 \approx 1120.07 \, \text{MeV} \] ### Final Answer The Q value of the induced fission reaction is approximately **1120.07 MeV**.

To calculate the ground state Q value of the induced fission reaction given by the equation: \[ n + _{92}^{235}U \rightarrow _{92}^{236}U \rightarrow _{40}^{99}Zr + _{52}^{134}Te + 2n \] we will follow these steps: ### Step 1: Understand the Q value formula The Q value of a nuclear reaction is given by the equation: ...
