The decomposition of ozone is believed to occur by mechanism :
`O_3 rightarrow O_2+O`(fast)
` O+O_3 rightarrow 2O_2`
When the concentration of `O_(2)` is increased. The rate of decomposition of ozone ……. .

Options

A. increases
B. decreases
C. remains the same
D. cannot be answered

Answer

B

Explanation

Rate`=k'[O][O_(3)],K=([O_(2)[O])/([O_(3)]),` So `[O]=(K[O_(3)})/([O_(2)])`
`=k'K[O_(3)]^(2)//[O_(2)]`
