Q: For a zero-order reaction, how does the concentration of reactants change over time? (2020)

Solution: In a zero-order reaction, the concentration of reactants decreases linearly with time.

Steps: 5

Step 1: Understand that a zero-order reaction means the rate of reaction is constant and does not depend on the concentration of reactants.
Step 2: Know that in a zero-order reaction, the concentration of the reactants decreases at a steady rate over time.
Step 3: Visualize this decrease as a straight line when you plot concentration against time on a graph.
Step 4: Remember that the formula for a zero-order reaction is [A] = [A]0 - kt, where [A] is the concentration at time t, [A]0 is the initial concentration, k is the rate constant, and t is time.
Step 5: Conclude that since the concentration decreases linearly, it means that for every unit of time, the concentration decreases by a fixed amount.
