Question:

the basis of the method of initial rates used in this experiment is that the concentrations of reagents are essentially unchanged during the measurement time period. calculate the % of the initial (NH ₄) ₂S ₂O ₈ that has reacted when the blue colour appears

C _KI= 0.016

C _(NH4)2S2O8= 0.024

C _{NaS2O3= 0.00014}
