Question
Which of the following statements is not correct?
A.
For a zero order reaction, $${t_{\frac{1}{2}}}$$ 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 $$mo{l^{1 - n}}\,{L^{n - 1}}\,{s^{ - 1}}$$ where $$n$$ is order of the reaction.
D.
The unit of rate of reaction changes with order of reaction.
Answer :
The unit of rate of reaction changes with order of reaction.
Solution :
The unit of rate of reaction is $$mol\,{L^{ - 1}}\,{s^{ - 1}}.$$ It does not change with order.
