The    integrated    rate    equation    is \[kt=\log \,{{C}_{0}}-\log {{C}_{t}}\]. The straight line graph is obtained by plotting

A)  \[\log {{C}_{t}}\] vs time

B)  \[\frac{1}{time}vs\,\,{{C}_{t}}\]

C)  time \[vs\,\,{{C}_{t}}\]

D)  \[\frac{1}{time}vs\frac{1}{{{C}_{t}}}\]

Correct Answer: A

Solution :

                For first order reaction, Integrated rate equation,\[kt=\log \,{{C}_{0}}-\log \,{{C}_{t}}\] The straight line graph is obtained by plotting \[\log \,{{C}_{t}}\]/ versus time.
