Problem

Which one of the following is not a redox reaction?

a. 2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g)

b. H2(g) + Cl2(g) → 2HCl(g)

c. 2H2O2(aq) → 2H2O(l) + O2(g)

d. Fe2O3(s) + 3H2SO4(aq) → Fe2(SO4)3(aq) + 3H2O(l)

e. 2KMnO4(aq) + 10FeSO4(aq) + 8H2SO4(aq) → K2SO4(aq) + 2MnSO4(aq) + 5Fe2(SO4)3(aq) + 8H2O(l)
