To explore if substance A influences the reaction rate of the colored liquids X and Y, the researcher should first record the duration it takes for the mixture to clear when X and Y are combined. Next, he should assess how long it takes for the same result after incorporating substance A into the mixture of X and Y. This will help establish if substance A serves as an enzyme.
