Question

A student proposed the following mechanism for the gas phase reaction of fluorine with chlorine dioxide. ..... step 1 ..... fast: ...... 2 ClO2 Cl2O4 ..... step 2 ..... slow: .... Cl2O4 F2 2 FClO2 (1) What is the equation for the overall reaction

Answer 1

Step-by-step explanation:

As the given equations are as follows.

Step 1:
`2ClO_(2) \rightleftharpoons Cl_(2)O_(4)` (fast)

Step 2:
`Cl_(2)O_(4) + F_(2) \rightarrow 2FClO_(2)` (slow)

So, in order to determine the overall reaction we will add both step 1 and step 2 as follows.

Step 1 + 2 :
`2ClO_(2) Cl_(2)O_(4) + F_(2) \rightleftharpoons Cl_(2)O_(4) + 2FClO_(2)`

Thus, by cancelling the common species we can conclude that the equation for overall reaction is
`2ClO_(2) + F_(2) \rightarrow 2FClO_(2)`.
