For a zero-order reaction, which statement is true?
A.The rate is independent of reactant concentration
B.The half-life is independent of [A]₀
C.ln[A] falls linearly with time
D.The rate doubles when [A] doubles
Explanation
Core Concept
Zero order means rate = k, constant until the reactant runs out. [A] falls linearly with time because the rate never slows.
Correct Answer
AThe rate is independent of reactant concentration
