Q.
For a reaction $3 A \to 2 B,$ the average rate of appearance of B is given by $\frac{Δ [B]}{Δ t} .$

The correct relation between the average rate of appearance of B with the average rate of disappearance of A is given in option [2023]

1 $\frac{- Δ [A]}{Δ t}$

2 $\frac{- 3 Δ [A]}{2 Δ t}$

3 $\frac{- 2 Δ [A]}{3 Δ t}$

4 $\frac{Δ [A]}{Δ t}$

Ans.
(3)

$3 A \to 2 B$

$r = - \frac{1}{3} \frac{Δ [A]}{Δ t} = + \frac{1}{2} \frac{Δ [B]}{Δ t} \Rightarrow \frac{Δ [B]}{Δ t} = - \frac{2}{3} \frac{Δ [A]}{Δ t}$

Solution

Q. For a reaction 3A→2B, the average rate of appearance of B is given by Δ[B]Δt. The correct relation between the average rate of appearance of B with the average rate of disappearance of A is given in option [2023]

1 -Δ[A]Δt

2 -3Δ[A]2Δt

3 -2Δ[A]3Δt

4 Δ[A]Δt

Ans. (3) 3A→2B r=-13Δ[A]Δt=+12Δ[B]Δt⇒Δ[B]Δt=-23Δ[A]Δt
