Question

What is the graph of $\left\{\frac{1}{\left[A\right]}\right\}$ vs time for second order reaction looks like?

• A.
• B.
• C.

Answer 1

The correct option is C

Rate equation of the second order reaction is $\frac{1}{\left[A\right]}=\frac{1}{[A{]}_0}+kt$
Where [A] is concentration at time t and $[A{]}_0$ is initial concentration.
As graph is asked for $\frac{1}{\left[A\right]}$ vs t and we can easily compare and see that rate equation of second order reaction is in the form of y= mx+c. when time $t=0,\frac{1}{\left[A\right]}=\frac{1}{[A{]}_0}$
