QNEET-2023-Ch-276: NEET 2023 Chemistry - Class 12 NEET-2023-Ch-276 Solution: For a reaction \(3A 2B\) The average rate of appearance of B is …

For a reaction 3A→2B3A \rightarrow 2B The average rate of appearance of B is given by Δ[B]Δt\frac{\Delta[B]}{\Delta t}. The correct relation between the average rate of appearance of B with the average rate of disappearance of A is given in option: −Δ[A]Δt-\frac{\Delta[A]}{\Delta t} 3Δ[A]2Δt\frac{3\Delta[A]}{2\Delta t} −2Δ[A]3Δt-\frac{2\Delta[A]}{3\Delta t} Δ[A]Δt\frac{\Delta[A]}{\Delta t}

Multiple Choice Options

  • A −Δ[A]Δt\frac{-\Delta[\mathrm{A}]}{\Delta \mathrm{t}} _ t _ _ [ A ] _
  • B −3Δ[A]2Δt\frac{-3 \Delta[\mathrm{A}]}{2 \Delta t} 2_ t _ 3_ [ A ] _
  • C −2Δ[A]3Δt\frac{-2 \Delta[\mathrm{A}]}{3 \Delta \mathrm{t}} 3_ t _ 2_ [ A ] _
  • D Δ[A]Δt\frac{\Delta[\mathrm{A}]}{\Delta t} _ t _ [ A ] _

Step-by-Step Verified Solution

3   A _ 2   B r = _ 1 3 _ [ A ] _ t = + 1 2 _ [ B ] _ t + _ [ B ] _ t = _ 2 3 _ [ A ] _ t
