A) \[{{[A]}_{o}}=[A]\,{{e}^{-Kt}}\]
B) \[K={{[A]}_{o}}{{e}^{-A/t}}\]
C) \[Kt=2.303\,\log \,\frac{{{[A]}_{o}}}{[A]}\]
D) \[\log \,\frac{{{[A]}_{o}}}{[A]}=-2.303\,Kt\]
Correct Answer: C
Solution :
Integrated velocity equation for first order reaction is: \[k=\frac{2.303}{t}\log \frac{{{(A)}_{o}}}{(A)}\]
