• # question_answer The variation of concentration of the product P with time in the reaction, $A\to P$ is shown in following graph. The graph between $\frac{-\,d[A]}{dt}$and time will be of the at type A) B) C) D)

 As from the given graph, it is clear that the concentration of the product increases linearly with time (, thus order of the reaction $=0\,and-\frac{d\left[ A \right]}{dt}=cons\tan t$ Thus correct plot is given option [a].
