Absorption is directly related to the concentration of FeNCS^2+ (aq) in the experiment. When I mixed Fe^3+ (aq) with NCS^-, the solution resulted in FeNCS^2+, which produced a red color. I then used a colourimeter to measure the FeNCS^2+ absorption values. I used the values to make a graph that provided me with a calibration curve that gave a linear equation that I was able to use to calculate the concentrations of the species in my solutions, with the help of an ICE table. Once I had the concentrations of my species, I then was able to plug in the values into the Kc formula and calculate the Kc values for all my solutions. The mixing of the volumes was a tricky situation, where one had to be exact or the concentrations of the solutions would be off. Also since the Kc is affected by temperature, it was important to maintain a constant temperature. Seen as a change in temperature will cause a change in equilibrium.

He was so helpful and cheerful! I loved his energy so much! Other tutors had begun to confuse me, but he was the one who finally made my problem make sense to me. He even provided me with an extra link to help me in the future.

He provided me with help on my assignment but had a hostile attitude. he also told me we would not have time for both of my questions but we were only 15 minutes in the session.

The concepts just weren't being explained in a way that I understood. The answers felt a little vague and I just didn't understand.

Very thankful for Tutor.com. Especially in my harder classes like chemistry. Since my class is online and I do not have instant access to my teacher the tutors on this site really help me gather a better understanding.
