Q: What is the effect of increasing the concentration of a reactant in a first-order reaction?

Solution: In a first-order reaction, increasing the concentration of a reactant results in a linear increase in the rate.

Steps: 5

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, the rate of the reaction will also increase.
Step 4: Understand that this increase in rate is directly proportional, meaning if you double the concentration, the rate will also double.
Step 5: Conclude that increasing the concentration of a reactant in a first-order reaction leads to a linear increase in the rate of the reaction.
