(P) For $3^{\text{rd }}$ order

Time

$$kt=\frac{1}{3-1}\left[\frac{1}{A_t^2}-\frac{1}{A_0^2}\right]$$

$$2kt=\frac{1}{A_t^2}-\frac{1}{A_0^2}$$

$$\frac{1}{A_t^2}=2kt+\frac{1}{A_0^2}$$

(P) $\to$ (3) order 3

for order- $3\to t_{1/2}\propto \frac{1}{[A_t{]}^2}$ (P) $\to$ (2)

(P) $\to$ (2,3)

(Q) $A_t=A_0-k_t$ (for zero order)

${\mathrm{t}}_{1/2}\propto \left[{\mathrm{A}}_{\mathrm{t}}\right]$

 (Q) → 1, 4

(R) Slope $=\tan \theta =-2$

${\log }_{}{\mathrm{t}}_{1/2}=-2{\log }_{}\left[A\right]+{\log }_{}C\left\{y=mx+c\right]$

${\log }_{}{\mathrm{t}}_{1/2}={\log }_{}\left[\frac{C}{{\left[A\right]}^2}\right]takinganti{\log }_{}$

$$R\to 3^{rd}Order$$

 Valid for all order

 (S) → 1, 3
