Which one of the following chemical changes illustrates a redox process?

1. XeF4 + O2F2 → XeF6 + O2
2. XeF2 + PF5 → [XeF]+ PF6−
3. XeF6 + H2O → XeOF4 + 2HF
4. XeF6 + 2H2O → XeO2F2 + 4HF

Correct answer: XeF4 + O2F2 → XeF6 + O2

Solution

This reaction involves the transfer of electrons, where xenon is oxidized from XeF4 to XeF6 and oxygen is reduced from O2F2 to O2, demonstrating the characteristics of a redox process.
