Conversion of oxygen into ozone is non-spontaneous at

Options

  1. Ahigh temperature
  2. Blow temperature
  3. Call temperatures
  4. Droom temperature

Correct answer

C. all temperatures

Step-by-step solution

Conversion of oxygen into ozone is endothermic process ( H =+ ve ) and proceeds through decrease in entropy ( S =- ve )3 O ₂(g) 2 O ₃(g) G = H - T S G =+ ve Therefore, reaction is non-spontaneous at all temperatures
