Please help me.
Transcribed Image Text:1. Reaction: Fe²+→>Fe(OH)3(s)
2. The rate constant for the reaction is 0.273 min-¹.
3. The current concentration of Iron (II) is 60 mM. But in order
to discharge, the concentration must be 0.1 mM. How long
must the reaction proceed to reach this concentration?
Expert Solution
Step 1
Given a reaction , Fe2+ → Fe(OH)3 , and the rate constant of the reaction is 0.273 min–1
Given concentration of iron (ii) at the time is 60 mM , in order to discharge concentration will be 0.1 mM .
We have to calculate the time required when concentration of iron (ii) will be reached at 0.1 mM .
