18. The reverse reaction of sulfur dioxide and oxygen forming sulfur trioxide would be the decomposition of sulfur trioxide to sulfur dioxide and oxygen.
1 answer
That is incorrect. The reverse reaction of sulfur dioxide and oxygen forming sulfur trioxide (SO2 + O2 -> 2SO3) would be the combination of sulfur dioxide and oxygen to produce sulfur trioxide. The decomposition reaction of sulfur trioxide would result in the formation of sulfur dioxide and oxygen.
