A) \[\lambda \]
B) \[\frac{2\eta }{\lambda }[1-{{e}^{-\lambda t}}]\]
C) \[\frac{\eta }{2\lambda }[1-{{e}^{-\lambda t}}]\]
D) \[\frac{\eta }{{{\lambda }^{2}}}[1-{{e}^{-{{\lambda }^{2}}t}}]\]
Correct Answer: B
Solution :
Consider the reaction \[_{1}{{H}^{2}}{{+}_{1}}{{H}^{2}}{{\to }_{2}}H{{e}^{4}}+Q\] \[\Delta m=m{{(}_{2}}H{{e}^{4}})-2m{{(}_{1}}{{H}^{2}})\] \[={{A}_{2}}-2{{A}_{1}}\] Since, \[Q=\Delta m{{c}^{2}}=({{A}_{2}}-2{{A}_{1}}){{C}^{2}}\]
