Question

Which of the following represents the correct graph between rate of reaction and concentration for a first order reaction?

• A.
• B.
• C.
• D. None of the above

Answer 1

The correct option is B

For a $n^{th}$ order reaction , rate (R):
$R=k[A{]}^n$
Zero order reaction:
$n=0$
$R=k[A{]}^0=k$
Rate is independent of concentration. so, the graph for zero order is:
For first order :
$n=1$
$R=k[A{]}^1$
$y=mx$ graph
