Question

The redox reaction between hydrogen peroxide, H₂O₂, and permanganate ions, MnO₄^-, in acid solution are as follows:

5H₂O₂(aq) + 2MnO₄^-(aq) + 6H⁺(aq)  →   5O₂(g) + 2Mn²⁺(aq) + 8H₂O (l)

5 mol of MnO₄^-was required to reach the equilibrium. How many moles of H₂O₂were required to reach the equilibrium?

a) 2 mol                           

b. 10 mol

c) 12.5 mol           

d) 25 mol

Answer 1

wus my MUM rea Question :- Redox reaction : 5 May cap. 2 + 2 mm 07. cap.) + 6H@ag.) — 502(9) + 2 renztag te moll) We know that - - 5 modes of muon was required to reach equilinium To find :- How many moles of Holz were required to reach equilibrium: Solution: from equation :- 4 when 2 units of muou were - utilised then 5 units of th02 are also required , # This means, according to giren condition, # "2 units = 5 mol of mno ç 1 given) 1. (nuoro ) # so one unit e çmol. (using unitary metod) Mow. 5 units = 5 )x5 wire e (H2O2) = 25 = 12.5 mol VW Wir Thanks! Please rate! Aus :- 6 12.5 mol в 4,", але тешлеd reach the equilibrium.
