Show that, with appropriate coefficients, the two reactions can be summed to give the overall oxidation of so2 by o2 to give so3. give the equation for the final overall oxidation of so2 by o2 to give so3 as your answer.

Explanation:

It is known that the oxidation of to is catalyzed by . In this process, two steps are involved as follows.

(a)    

whereas, the second step is

(b)    

Balancing the above reaction by multiplying equation (a) by 2 as follows.

(c)    

Now, on adding both  reaction equations (b) and (c) the net reaction equation will be as follows.

Thus, we can conclude that the equation for the final overall oxidation of by to give is as follows.

elements make up everything, and they combine to make compounds.

the answer is c
