JEE MainChemistryChemical Kinetics and Nuclear ChemistryMCQ+4 / −1
For a reaction 12A→2B{1 \over 2}A \to 2B21​A→2B rate of disappearance of ‘A’ is related to the rate of appearance of ‘B’ by the expression
  1. A
    −d[A]dt- {{d[A]} \over {dt}}−dtd[A]​=12d[B]dt{1 \over 2}{{d[B]} \over {dt}}21​dtd[B]​
  2. B
    −d[A]dt- {{d[A]} \over {dt}}−dtd[A]​=14d[B]dt{1 \over 4}{{d[B]} \over {dt}}41​dtd[B]​
  3. C
