Question

In a reaction of acidified H,O, with KI, the concen- tration of 1, formed rises from 0 to 10-5 mol dm- in 10 sec. The rate of reaction is (1) 10-6 mol dm-3 s-1 (2) 10-5 mol dm-3 s-1 3 (3) 10-4 mol dm-3 s-1 (4) 10-3 mol dm-3 s-1​

Answer 1

Answer:

The reaction is

2I−+H2O2+2H+⟶I2+2H2O

Rate =+dtd[I2]=1010−5=10−6 mol dm−3 s−1
