Question

Which of the following statement is not correct?

• A. In zero order reaction, the rate of the reaction remains constant through out
• B. A second order reaction would becomes a pseudo first order reaction, when one of the reactants is taken in large excess
• C. The units of first order rate constant depends on the units of the concentration terms used
• D. In the first order reaction, the plot of log $(a-x)$ vs time follows straight line equation

Answer 1

Answer: (C)

In actual, unit of rate constant is independent of unit of concentration. The unit of $K$ is $s^{-1}$
