I'm stuck on this homework problem I have...
"How long does it take in MINUTES to reduce the concentration of tris(1,10 Phenanthrolone) Iron (II) Complex ion to 10% of its initial value?"
I've been given the equation: Rate = - (Delta) [Fe(phen)3 2+] / (Delta) time
So I think its the negative change in concentration of the [Fe(phen)3 2+] divided into the change in time...
My question is how do I set this equation up? Here are some figures from previous questions that I've found...
Rate = K[A]^1
K = (8.28x10^-3 Moles x Minutes)
[A] = Initial concentration of the "tris" complex ion (1,10 phenanthroline) = (5.5x10^-5 M/L)
Rate = (4.5x10^-7 M/min)
Also the used in the experiment were:
15.0 ml of 0.00100M Fe2+
15.0 ml of 0.00100M 1,10 Phenanthroline
10.0 ml of 0.100M NaOH
60.0 ml of H2O
I don't know how to set it up or what figures I need to use, so if anyone can help me I would be very very greatful.
