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 $\log\frac{k_{2}}{k_{1}} = \frac{E_{ga}}{2.303R}\left\lbrack \frac{T_{2} - T_{1}}{T_{1}T_{2}} \right\rbrack$
• 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 the order of reaction.

Answer 1

Answer: (D)

The unit of rate of reaction changes with the order of reaction.

Answer 2

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