Abstract (250 words)
An absorption probe from LabQuest was used to measure the reaction rate of acetone with iodine in the context of hydrochloric acid, a catalyst. The rate of reaction may be varied by varying the reaction rate. There is no correlation between the response rate and the reaction conditions, as shown by these findings. The transmittance and absorption of reactants with catalyst are being measured in this experiment to estimate the reaction rate among acetone and iodine. To put it simply, the response is recorded, and the reaction continues until the solution’s color is no longer visible. This is done for five solutions with varying concentrations of the two chemicals. A laboratory-built spectrophotometer was used to investigate the kinetics of the color-changing iodination of acetone within the presence of an acid catalyst. Using a commercial spectrophotometer, these findings would have yielded the same results. We want to find out whether or not this response is nil, first, or second order. The rate law may be calculated by systematically altering the reactants’ concentration. An absorption vs. time plotting with a regular fit for rate law also helped pinpoint the reaction sequence. To create one graph for the start and end of each reaction, information was projected from separate graphs of absorbance with time. A sample plot in the attachment illustrates the iodine concentrations before and after the response started and absorbance before and after stabilization.
