Suppose that a different student obtained reaction rates for the particle-size experiment, and that these rates did not show a pattern. Check all possible sources of this error. Some of the broken tablet was not added to the water. The tablet was not crushed enough to make a substantial difference. The size of the reaction beaker was varied. The tablets were not uniform in their mass.

Short Answer

To enhance the efficiency of a reaction when using a tablet, ensure all pieces are utilized, crush the tablet finely to increase surface area, and use uniform tablets to maintain consistent mass, leading to predictable and controlled results.

Step-by-Step Solution

Step 1: Ensure All Parts of the Tablet Are Used

Make sure to add all broken pieces of the tablet to the water to avoid slowing down the reaction rate. If some parts are left out, it reduces the overall mass that can react. This can result in a less vigorous reaction, so complete usage is essential for effective results.

Step 2: Crush the Tablet Properly

Crushing the tablet adequately is crucial as it increases the surface area, allowing more parts of the tablet to be exposed to the water. A greater surface area means that more of the tablet reacts at once, speeding up the reaction. Ensure that the tablet is crushed finely enough to maximize this effect.

Step 3: Use Uniform Tablets

The mass of the tablets should be consistent for optimal reaction rates. Tablets of varying sizes can either speed up or slow down the reaction depending on their weight. Using tablets that are uniform ensures predictable results and more controlled reactions, which is important for accuracy.
