Question

For a certain chemical reaction variation in the concentration ln $[R]$ vs. time plot is given alongside.For this reaction:

What is the order of the reaction?
What are the units of rate constant $k$?
Give the relationship between $k$ and $t1/2$ (half-life period).
What is the slope of the curve?
Draw the plot log $[R]0 /[R]$ vs time $t(s)$.

✓

Answer

First order.
$Time^{-1} (s^{-1})$
$\text{k}=\frac{0.693}{\text{t}_{1/2}}$
Slope = - k (rate constant).
