Question

A student hypothesizes that the rate of a chemical reaction will increase as the concentration of the reactants increases. To test his hypothesis, the student performs an investigation. Which are the independent and the dependent variables in the investigation?

Answer 1

independent variable- concentration of reactants

dependent variable- rate of reaction

Step-by-step explanation:

A dependent variable is a variable that is placed under test and is measured under the process of a scientific experiment.

An independent variable is a variable that undergoes the change in the experiment performed. This change is done with respect to test the efforts that are observed on the dependent variable.

In the given hypothesis, 'concentration of reactants' is the independent variable and 'rate of reaction' is the dependent variable
