NEET Chemistry Redox Reactions Questions Solved


In the reaction CrO5 + H2SO4 → Cr2(SO4)3 + H2O + O2 one mole of CrO5 will liberate how many moles of O2

(1) 5/2

(2) 5/4

(3) 9/2

(4) none of these

(4) The balance reaction is

4CrO5 + 2H2SO4 → 2 Cr2 (SO4)3 + 2H2O + O2

∴ 1 mole CrO5 can liberate only 14 mole O
