  3. Inversely with time
  4. Remains constant

Questions & Step-by-Step Solutions

In a zero-order reaction, how does the concentration of the reactant change over time?
  • Step 1: Understand that a zero-order reaction means the rate of the reaction does not depend on the concentration of the reactant.
  • Step 2: Know that in a zero-order reaction, the rate of reaction is constant over time.
  • Step 3: Realize that because the rate is constant, the amount of reactant decreases by the same amount in each equal time interval.
  • Step 4: Visualize this decrease as a straight line when you plot concentration against time on a graph.
  • Step 5: Conclude that the concentration of the reactant decreases linearly over time.
