Q
Q: Which of the following statements about reaction rates is true?
Solution:
Reaction rates can change with time as reactants are consumed and products are formed, affecting the concentration of reactants.
Steps: 5
Show Steps
Step 1: Understand that a reaction rate is how fast a chemical reaction happens.
Step 2: Recognize that during a reaction, reactants (the starting materials) are used up.
Step 3: Note that as reactants are consumed, their concentration (amount) decreases.
Step 4: Realize that as products (the substances formed) are created, their concentration increases.
Step 5: Understand that the change in concentration of reactants and products over time affects the overall reaction rate.
