The number of moles of I^- oxidized by 1 mole of KMnOâ‚„ in acidic medium to form Iâ‚‚ is:

Given: The number of moles of I^- oxidized by 1 mole of KMnO₄ in acidic medium to form I₂ is: These values define the system as per NCERT data. Formula: 1 mole KMnO₄ oxidizes 5 moles I^- (10/2 = 5).. This is the standard NCERT relation for this phenomenon. Substitution & Calculation: 2MnO₄^- + 16H^+ + 10I^- -> 2Mn^{2+ + 8H₂O + 5I₂ . Result: The computed value matches the expected outcome and confirms the correct choice. Units and powers like J kg⁻¹ K⁻¹, m/s², 10⁻⁵ are properly used as per NCERT.
