q3

3. (5 pts) Consider the following reaction H ,02(aq) +31-(aq) + 2H + (aq) 13 (aq) + 2H20(1) The rate of appearance of H2O was found to be 1.40 × 104 M/s. What is the rate of disappearance of I?

Solution

as per the reaction d[H2O]/2dt= -d[I-]/3dt

given d[H2O]/dt= 1.4*10^-4 M/s

hence -d[I-]/dt= rate of disappearance of I- = 1.4*10^-4*3/2= 2.1*10^-4 M/s
