The average rate of disappearance of ozone in the reaction 2o3(g) → 3 o2(g) is found to be 7.91×10–3 atm over a certain interval of time. what is the rate of appearance of o2 during this interval?

11.865 x 10⁻³ atm over a certain interval of time.

Explanation:

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.

its first and third is your answer i did the qustion the fourth isnt right
