Answer:
11.865 x 10⁻³ atm over a certain interval of time.
Explanation:
- As the reaction: 2O₃ → 3O₂,
- The rate of the reaction = - d[O₃] / 2dt = d[O₂] / 3dt,
where, (- d[O₃] / dt) is the rate of disappearance of ozone = 7.91 × 10⁻³ atm over a certain interval of time,
(d[O₂] / dt) is the rate of appearance of O₂.
∴ The rate of appearance of O₂ = (d[O₂] / dt) = (- 3d[O₃] / 2dt) = 3(the rate of disappearance of ozone) / 2 = [3 ( 7.91 × 10⁻³ atm over a certain interval of time] / 2 = 11.865 x 10⁻³ atm over a certain interval of time.
