Observe the graph shown in figure and answer the following questions :
(a)
What is the order of the reaction ?
(b)
What is the slope of the curve?
(c)
Write the relationship between $\displaystyle k$ and $\displaystyle t_{1 / 2}$ (half life period)
Marking-scheme solution
(a) First order
(b) Slope \(\displaystyle =\mathrm{k} / 2.303\)
(c) \(\displaystyle \mathbf{k}=\frac{0693}{t_{1 / 2}}\)
