Question

Which of the following Statements, about zero order reaction is not true?

• A. Its rate constant unit is $s^{-1}$
• B. The graph between time and rate of reaction is a straight line
• C. Rate of reaction is independent of concentration of reactants
• D. None of the above

Answer 1

Answer: (A)

For zero order reaction $r=k[\text{ conc }{]}^{\circ }$
$\therefore$ Units of $k$ are $mol{L}^{-1}tim{e}^{-1}$
$\therefore$ The statement that unit of rate constant for zero order reaction is $s^{-1}$ is wrong.
It is intact unit of $k$ for first order reaction.
The other statements are correct.
