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.

All of these things affect the reaction rate of the tablet. Not adding all of the broken tablet will likely slow down the reaction rate. Not crushing the tablet enough may also affect the reaction rate because of surface area. Crushing the tablet more will increase its surface area, since more surface of the tablet is created. This will increase the reaction rate because more exposed area will react with the combined substance. Tablets not being having the same mass may speed up or slow down the reaction rate, depending on whether the tablet is bigger or smaller, since there is more or less of the tablet to dissolve.

Incase you're doubtful of my answers. Here's proof it's on Edge.

What is an Experimental Error ?

Experimental error is the difference between a measured value and its true value. In other words, it is the inaccuracy or inaccuracies that stop us from seeing an absolutely correct measurement.

Experimental error is very common and is to some degree inherent in every measurement.

Therefore, The possible sources of the error obtained in the results of different students are ; Some of the broken tablet was not added to the water, The tablet was not crushed enough to make a substantial difference, The tablets were not uniform in their mass.Hence The correct options are (A), (B) and (D)
