The addition of N0 as a catalyst to a mixture of S02 and 02 speeds up the following reaction: S02 + ½02 � S03
The following reactions could be involved in the process.
- N2 + 02 � 2N0
- ½N2 + 02 � N02
- N0 + ½02 � N02
- N02 � N0 + ½02
- S02 + N0 � S03 + ½N2
- S02 + N02 � S03 + N0
Which one of the following shows the most likely course of the overall reaction?
Answer:
26) B
We know that a catalyst always remains unchanged at the end of a reaction. This means that at the end of the reaction, NO must be recovered. Hence, reaction 6 will definitely be one of the reactions.
Since 6 is only mentioned in option B, B is the answer.
