Answer:
The correct answer is 2SO3=>2SO2+O2
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:
A+B=>C+D
Now ,the reverse reaction for this will be:
C+D=>A+B
•According to the question:
sulfur dioxide and oxygen are reacting together to form sulfur trioxide. The forward reaction for this will be:
2SO2+O2=>2SO3
The reverse reaction for this will be :
2SO3=>2SO2+O2
Hence,the correct answer is option D.
