Answer 2

When measuring reaction time, it is best to start the timer when both reactants are first mixed.

Step-by-step explanation:

In order to measure the reaction time, t, in a chemical reaction, it is best to start the timer when both reactants are first mixed.

Starting the timer when both reactants are mixed ensures that the reaction is initiated and the timer captures the time it takes for the reaction to proceed. This method provides a more accurate measurement of the reaction time compared to starting the timer when other events, such as adding an indicator or heating the reactants, occur.

Therefore, the correct answer is option b. Start the timer when both reactants are first mixed.
