From the log graph,

the slope of the graph is = \frac{-2.46-1.79}{3200}
                                          = -k/2.303                             ..(from log equation)       

On comparing both the equation we get,

-k/2.303 = -0.67/3200
   k= 3200\times (0.67/3200)
   k= 4.82 \times 10^{-4}\ s^{-1}
