Final answer:
Temperature, concentration of reactants, and the presence of catalysts are all factors that can influence reaction rates, so more than one response is correct.
Step-by-step explanation:
The rates at which chemical reactions occur can be influenced by various factors, such as the temperature of the reactants, the concentration of reactants, and the presence of catalysts. All of these factors have the potential to impact reaction rates.
Increasing the temperature generally increases the energy of the reacting molecules, leading to more frequent and more intense collisions, thus increasing the reaction rate. Similarly, a higher concentration of reactants corresponds to a greater number of reactant molecules in a given volume, leading to more frequent collisions and an increased reaction rate. A catalyst provides an alternative pathway with a lower activation energy for the reaction, which significantly speeds up the rate without being consumed in the process.
Based on this information, the correct answer to the student's question of which will influence all reaction rates is D) More than one response is correct, as temperature, concentration, and catalysts all can affect reaction rates.
