The reaction, \(2 \mathrm{SO}_{2}(g)+\mathrm{O}_{2}(g) \rightleftharpoons 2 \mathrm{SO}_{3}(g)\) is carried out in a \(1 \mathrm{dm}^{3}\) vessel and \(2 \mathrm{dm}^{3}\) vessel separately. The ratio of the reaction velocities will be
- A \(4: 1\)
- B \(8: 1\)
- C \(1: 8\)
- D \(1: 4\)
Answer & Solution
Correct Answer
(B) \(8: 1\)
Step-by-step Solution
Detailed explanation
The rate law expression is, \(r=k\left[\mathrm{SO}_{2}\right]^{2}\left[\mathrm{O}_{2}\right]\) As, volume increase 2 times, concentration reduces by \(\frac{1}{2}\) times i.e., \(\left[\mathrm{SO}_{2}\right]_{1}=\left[2 \mathrm{SO}_{2}\right]\) and…
