Question:

Which of the following is a true statement for a zero order reaction?

Options:

The reaction rate is doubled when the initial concentration is doubled.

The time for half change is half the time taken for completion of the reaction.

The time for half change is independent of the initial concentration.

The time for completion of the reaction is independent of the initial concentration.

Correct Answer:

The time for half change is half the time taken for completion of the reaction.

Explanation:

The reaction whose rate does not depend upon the concentration of reactants is called a zero order reaction.

Integrated rate equation for a zero order reaction is [R] = -kt + [R]0
