Question: What effect does increasing the concentration of a reactant have on the rate of a first-order reaction?

Options:

Correct Answer: Increases the rate

Solution:

Increasing the concentration of a reactant in a first-order reaction increases the rate of the reaction.

What effect does increasing the concentration of a reactant have on the rate of a first-order reaction?

What effect does increasing the concentration of a reactant have on the rate of a first-order reaction?

Step 1: Understand what a first-order reaction is. In a first-order reaction, the rate of the reaction depends on the concentration of one reactant.
Step 2: Know that the rate of a reaction is how fast the reactants turn into products.
Step 3: Realize that in a first-order reaction, if you increase the concentration of the reactant, you have more of that substance available to react.
Step 4: Understand that more reactant means more collisions between reactant molecules, which leads to more reactions happening.
Step 5: Conclude that increasing the concentration of the reactant will increase the rate of the reaction because there are more opportunities for the reactants to react.
