Scott B. Roberts Chem 201/L ESCG1 The purpose of the ESCG1 experiment was two fold. It initially involved learning some basic techniques in using the excel program by being guided through a tutorial initially. The second phase of the experiment involved taking concentration as a function of time data, in 3 different formats to derive which function created a linear relationship. The purpose of the experiment is to understand the relation of time as a function of concentration in three different formats: the concentration, the natural log of the concentration, and the reciprocal of the concentration. The data represents a zero order because the graph is linear in the Concentration as a function of time. Because the rate is in the zero order, the slope is equal to –k.

Unformatted text preview: RATE=K[A] . Rate Law: r=k All units cancel out for the constant K=-m To calculate the constant (k), you can find this different two ways. The easiest way is to just find a point on the line, because the constant is equal to –slope. The other way would be to take the change in concentration, final from initial, and then divide that by the change in time, final from initial. The experiment was helpful in a number of ways. First I was able to have a visual understanding of how to derive a rate law from given data. Also I had never used the excel software before, and found it to be very useful, especially in doing the calculations by formulas. I will probably use it more often in the future....
