KClO 3 + 6 FeSO 4 + 3 H 2 SO 4 → KCl + 3 Fe 2 ( SO 4 ) 3 + 3 H 2 O The above reaction was studied at 300 K by monitoring the concentration of FeSO 4 in which initial concentration was 10 M and after half an hour became 8 . 8 M . The rate of production of Fe 2 ( SO 4 ) 3 is _______ × l 0 – 6 mol L – 1 s – 1 (Nearest integer)

Correct answer

0

Step-by-step solution

KClO 3   +   6 FeSO 4   +   3 H 2 SO 4   →   KCl   +   3 Fe 2 ( SO 4 ) 3   +   3 H 2 O From the above equation, rate of decomposition FeSO 4 and rate of production of Fe 2 SO 4 3 can be written as follows, 1 6 × Rate   of   decomposition FeSO 4 = 1 3 × Rate   of   production Fe 2 SO 4 3 Rate of decomposition of FeSO 4 Change   in   concentration time   in   seconds = ( 10 - 8 . 8 ) 30 × 60 = 1 . 2 1800 &#1
