  1. A
    −d[A]2dt- {{d\left[ A \right]} \over {2dt}}−2dtd[A]​
  2. B
    −d[C]3dt- {{d\left[ C \right]} \over {3dt}}−3dtd[C]​
  3. C
    −d[B]dt- {{d\left[ B \right]} \over {dt}}−dtd[B]​
  4. D
    d[D]dt{{d\left[ D \right]} \over {dt}}dtd[D]​

Correct answer: B

Given,

2A + B →\to→ 3C + D

Rate of reaction =

−12d[A]dt=−d[B]dt - {1 \over 2}{{d\left[ A \right]} \over {dt}} = - {{d\left[ B \right]} \over {dt}}−21​dtd[A]​=−dtd[B]​ = 13d[C]dt=d[C]dt{1 \over 3}{{d\left[ C \right]} \over {dt}} = {{d\left[ C \right]} \over {dt}}31​dtd[C]​=dtd[C]​
