Question

question 11
a team of researchers is studying whether temperature affects the rate of a chemical reaction in the body. which statement about this experiment is not true?
the rate of the chemical reaction is the dependent variable.
the team should test multiple temperatures to see how it affects the reaction rate.
the input is the rate of the chemical reaction.
if temperature does affect the rate of the chemical reaction, then this relation is a function.

Explanation:

1. Dependent vs Independent Variables: In this experiment, temperature is the independent variable (the input being changed to test effects), and the chemical reaction rate is the dependent variable (the output being measured).
2. Experimental Design: Testing multiple temperatures provides more data on the relationship between temperature and reaction rate, which is a valid experimental practice.
3. Function Definition: If each temperature leads to exactly one reaction rate, the relationship meets the definition of a function.
4. Incorrect Statement: The input (independent variable) is temperature, not the reaction rate. The reaction rate is the measured output.

Answer:

The input is the rate of the chemical reaction.
