Answer to Question #228662 in Other for Ateufack Zeudom

Question

9, In the reaction 2O₃ → 3O_2(g) , the rate of appearance of Oxygen is 6.0 x 10^-5 M/s at a certain moment. What will be the rate of disappearance of O₃ at the same moment?

Answer 1

We have to calculate rate of disappearance of O₃ .

Rate = -1/2 ∆[O₃]/∆t = 1/3 ∆[O₂]/∆t 

We have ∆[O₂]/∆t = 6.0*10^-5 M/s 

So, 

-∆[O₃]/∆t = 2/3 * ∆[O₂ ]/∆t  

        = 2/3 * 6*10^-5 ===> 4*10^-5 M/s
