Experiment 3 Objective: To determine the Kinetics Law parameters n, k using integral method of analysis. This method allows one to use most or all of the experimental data in determining rate constants.
• total of 550 problems to solve with answer key.
However, one must first be certain of the reaction stoichiometry before attempting this kinetic analysis. In the following paragraphs, a series of linearization are presented depending on the reaction order. If the exact reaction order is uncertain, one may try several different linearizations.
The best fit should occur with the linearization that is appropriate for the data i.
Thus, the reaction rate constant is obtained from the slope of a plot of the molar concentration of "C" [Ct] versus reaction time. The intercept is, of course, the initial concentration [C]o. Thus, the experimental data are plotted with natural log of the concentration on the y-axis and time on the x-axis.
The reaction rate constant is simply the negative of the slope of this line, and the intercept is the natural log of the initial concentration. For second order reactions, the rate is proportional to one of the reactants to the 2nd power, or to two reactants, chemical reactions lab answers to the 1st power. For the former case the following rate equation holds. Thus, the experimental data are plotted as the reciprocal concentration y-axis versus time xaxis.

The reaction rate constant is simply the slope of this line, and the intercept is the reciprocal of the initial concentration. Adjust the conductivity meter probe inside the reactor and switch it ON for taking the reading of conductivity. Switch ON the reactor agitator and also adjust its rpm, note down the results on the interval of 3 minutes. Sr No. And capable of find out its slope with the help of hetero line equation and from its graph we discover that the instantly line occurs in first and chemical reactions lab answers order.
We discover that which order has reactons line with the given experimental values.
