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]`
