In dilute aqueous H 2 S O 4 , the complex diaquodioxalatoferrate(II) is oxidized by M n O 4 - For this reaction, the ratio of the rate of change of H + to the rate of change of M n O 4 - is
Correct answer
8
Step-by-step solution
The balanced chemical equation for the oxidation of the complex is as given below Mn O 4 - + 5 [ Fe H 2 O C 2 O 4 ) 2 2 - + 8 H + → 5 Fe H 2 O C 2 O 4 2 - + M n 2 + + 4 H 2 O Hence - d d t M n O 4 - = - 1 8 d d t H + d d t H + d d t M n O 4 - = 8 Rate of change of H + is 8 times the rate of change of M n O 4 - .
