Question

Which of the following statements is not correct?

• A. For a zero order reaction, $t_{1/2}$ is proportional to initial concentration.
• B. The relationship of variation of rate constant with temperature is given by $log \frac{k_{2}}{k_{1}}=\frac{E_{a}}{2.303R} \left[\frac{T_{2}-T_{1}}{T_{1}T_{2}}\right]$
• C. The unit of rate constant for a reaction is $mol^{1-n}$ $L^{n-1}$ $s^{-1}$ where $n$ is order of the reaction.
• D. The unit of rate of reaction changes with order of reaction.

Answer 1

Answer: (D)

The unit of rate of reaction is mol $L^{-1}$ $s^{-1}.$ It does not change with order.
