If sulfur dioxide and oxygen can be made into sulfur trioxide, what is the reverse reaction? a. so3 +o2à so3 b. 2so2 + o2à 2so3 c. 2so3à2so2+o2. d. so2+2so3à 3s +4o2

The correct answer is Option C.

Explanation:

Reverse reaction is defined as the chemical reaction in which the reactants forming products at first, react together to give back the reactants.

Forward reaction is given by the equation:

Now, the reverse reaction for this will be:

Sulfur dioxide and oxygen are reacting together to form sulfur trioxide. The forward reaction for this will be:

The reverse reaction for this will be:

Hence, the correct answer is Option C.
