Question

Four vessels 1, 2, 3 and 4 contain respectively, 10 g-atom ($t_{1/2} = 10 	ext{ h}$), 1 g-atom ($t_{1/2} = 5 	ext{ h}$), 5 g-atom ($t_{1/2} = 2 	ext{ h}$) and 2 g-atom ($t_{1/2} = 1 	ext{ h}$) of different radioactive nuclides. In the beginning, the maximum radioactivity would be exhibited by the vessel

Prashant Kotian · Accepted Answer

Correct answer: B. Activity . For vessel 1: . For vessel 2: . For vessel 3: . For vessel 4: . Vessel 3 has the highest ratio and thus the maximum radioactivity. Therefore, correct answer is B.
