Question

For the reaction, 2SO2 + O2 <=> 2SO3, the rate of disappearance of O2 is 2 × 10-4 mol L-1 s-1 . The rate of of appearance of SO3 is (A) 2 ×10-4 mol L-1 s-1 (B) 4 ×10-4 mol L-1 s-1 (C) 1 ×10-4 mol L-1 s-1 (D) 6 ×10-4 mol L-1 s-1

(Δ [O2]/Δ f) = 2 × 10-4 ([SO3]/Δ t) = 2 (Δ [O2]/Δ t) = 2 × 2 × 10-4 = 4 × 10-4 mol l-1 s-1

Q. For the reaction, $2 S O_{2} + O_{2} <=> 2 S O_{3},$ the rate of disappearance of $O_{2}$ is $2 \times 1 0^{- 4} m o l L^{- 1} s^{- 1}$ . The rate of of appearance of $S O_{3}$ is

$2 \times 1 0^{- 4} m o l L^{- 1} s^{- 1}$

$4 \times 1 0^{- 4} m o l L^{- 1} s^{- 1}$

$1 \times 1 0^{- 4} m o l L^{- 1} s^{- 1}$

$6 \times 1 0^{- 4} m o l L^{- 1} s^{- 1}$

$\frac{Δ [ O _{2} ]}{Δ f} = 2 \times 1 0^{- 4}$

$\frac{[ S O _{3} ]}{Δ t} = 2 \frac{Δ [ O _{2} ]}{Δ t}$

$= 2 \times 2 \times 1 0^{- 4}$

$= 4 \times 1 0^{- 4} m o l l^{- 1} s^{- 1}$
