Practice Questions: Zero Order Reaction
Question 1: Calculate the rate constant for a zero-order reaction if the reactant concentration was 0.070 M after 160 seconds and 0.025 M after 345 seconds.
Question 2: In a zero-order reaction, if the initial concentration of the reactant is 0.10 M and it decreases to 0.075 M, with a rate constant of 0.0030 mol L–1 s–1, how long will it take for this change to occur?
Question 3: A zero-order reaction has a rate constant of 0.005 M/s. If the initial concentration of the reactant is 2.0 M, calculate the concentration of the reactant after 50 seconds.
Question 4: For a zero-order reaction A →P, if the rate constant k is 0.01 M/s and the initial concentration of A is 3.0 M, determine the time taken for the concentration of A to decrease to 1.0 M.
Question 5: If a zero-order reaction has a rate constant of 0.0025 M/s, and the initial concentration of the reactant is 1.5 M, calculate the time required for the concentration of the reactant to decrease to 0.8 M.
Zero Order Reaction
Zero Order Reaction is a type of chemical reaction where the reaction rate does not change with variations in the concentration of the reactants. In such reactions, the concentration rates remain constant over time. This type of reaction is characterized by the fact that the concentration of the reactants does not influence the reaction rate.
