Answer: 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:
[tex]A+B\rightarrow C+D[/tex]
Now, the reverse reaction for this will be:
[tex]C+D\rightarrow A+B[/tex]
Sulfur dioxide and oxygen are reacting together to form sulfur trioxide. The forward reaction for this will be:
[tex]2SO_2+O_2\rightarrow 2SO_3[/tex]
The reverse reaction for this will be:
[tex]2SO_2\rightarrow 2SO_2+O_2[/tex]
Hence, the correct answer is Option C.
