Q78 / 200 · NEET 2003 · Chemistry

If the rate of the reaction is equal to the rate constant, the order of the reaction is:

  • Correct answer
    A
    0
  • B
    1
  • C
    2
  • D
    3

Solution

In first order reaction, $\begin{array}{l} -\frac{d x}{d t}=\mathrm{K}, \text { it means }-\frac{d x}{d t}=\mathrm{K}[\mathrm{A}]^{\circ} \\ =\mathrm{K} \end{array}$

Hence, the correct answer is option: 'A'.
