Case Study on AIIMS-SYLLABUS Chemistry syllabus Rate of a reaction
The Effect of Temperature on the Rate of a Reaction
Background: The rate of a chemical reaction is influenced by various factors, including temperature. In this case study, we will explore the effect of temperature on the rate of a reaction using the example of the reaction between hydrochloric acid (HCl) and sodium thiosulfate (Na2S2O3) solution.
Experiment: A student conducted an experiment to investigate how temperature affects the rate of this reaction. The student prepared several solutions: Solution A contained 50 mL of 0.1 M hydrochloric acid, and Solution B contained 50 mL of 0.1 M sodium thiosulfate solution. Both solutions were initially at room temperature (around 25°C).
The student set up a conical flask and placed it on a piece of paper marked with an “X.” They poured Solution A into the flask and then added Solution B. The reaction between the two solutions produced a yellow precipitate of sulfur. The student recorded the time it took for the X mark to disappear, indicating that the sulfur precipitate obscured it completely.
The experiment was repeated three times at different temperatures: 25°C (room temperature), 35°C (heating the solutions using a water bath), and 45°C (using a more intense heating method).
Results: The student recorded the following data:
Experiment 1: Temperature: 25°C Time for the X mark to disappear: 120 seconds
Experiment 2: Temperature: 35°C Time for the X mark to disappear: 75 seconds
Experiment 3: Temperature: 45°C Time for the X mark to disappear: 50 seconds
Analysis: The data obtained from the experiments demonstrate a clear trend. As the temperature increased, the time taken for the X mark to disappear decreased, indicating that the rate of the reaction increased.
This can be explained by the collision theory. According to the theory, as temperature rises, the kinetic energy of the reactant particles increases, leading to more frequent and energetic collisions between them. This results in an increased number of successful collisions, leading to a higher reaction rate.
The decrease in reaction time with increasing temperature can also be observed from the Arrhenius equation. The Arrhenius equation states that the rate constant (k) of a reaction is exponentially dependent on temperature (T). As the temperature increases, the exponential term in the equation becomes larger, resulting in a higher rate constant and thus a faster reaction rate.
Conclusion: This case study illustrates the effect of temperature on the rate of a chemical reaction. The results demonstrate that as the temperature increases, the reaction rate increases. Understanding the relationship between temperature and reaction rate is crucial for various fields, including industrial processes, environmental studies, and biochemical reactions.
Note: The case study provided here is fictional and intended for illustrative purposes only. Actual experimental procedures and results may vary depending on the specific reaction and experimental conditions.
