Get an original essayTheoryChemical equilibrium is the state in a chemical reaction in which the concentrations of the reactants and products remain constant over time. Le Chatelier's principle states that when a system in equilibrium is subject to a change, it will adapt to resist the change and establish a new equilibrium. The equilibrium constant, K, is a measure of the magnitude of a chemical reaction at equilibrium and reflects the concentration of reactants and products. It is a crucial parameter in determining the direction and magnitude of a reaction. Experimental methods The experiment was conducted using a spectrophotometer to measure the absorbance of the reaction mixture at different time intervals, from which the equilibrium constant was calculated using the Beer-Lambert law. Results and discussion The data collected during the experiment showed a clear trend in absorbance over time, allowing the calculation of the equilibrium constant. The obtained experimental value was compared with the theoretical value and the results were analyzed to determine the accuracy and precision of the experiment. Limitations and Sources of Error Possible sources of error in the experiment include instrumental errors, variations in sample preparation, and human errors in recording measurements. These factors may have influenced the accuracy of the results obtained in the experiment. Conclusion The experiment provided valuable information on the determination of equilibrium constants and the factors that influence them. The importance of equilibrium constants in predicting and manipulating chemical reactions was reaffirmed throughout the experiment. Please note: this is just an example.
