Conversion of oxygen into ozone is non-spontaneous at

  • A
    Iow temperature
  • B
    all temperature
  • Correct answer
    C
    high temperature
  • D
    room temperature

Solution

Ozone is not stable at high temperature. So, it decomposes into oxygen at high temperature. $2 \mathrm{O}_3 \longrightarrow 3 \mathrm{O}_2$ Thus, the reverse of this reaction is non-spontaneous at high temperature.

Hence, the correct answer is option: 'C'.
