1 . k = Ae - Ea/RT 2. rate = k n[ C ] n ⇒ ln rate = ln k n + n ln C 3. A arrow product a stackrel(1/2) h r longrightarrow (a/2) stackrel(1/2) h r longrightarrow (a/4) stackrel(1/2) h r longrightarrow (a/8) ⇒ 1 text st order reaction.

1 . k=Ae−Ea/RT 2. rate =kn​[C]n ⇒ ln rate =lnkn​+nlnC 3. A→ product a⟶21​hr​2a​⟶21​hr​4a​⟶21​hr​8a​ ⇒1st order reaction.

1 . $k = A e^{- E a / RT}$

2. rate $= k_{n} [C]^{n}$

$\Rightarrow$ ln rate $= ln k_{n} + n ln C$

3. $A \to$ product

$a ⟶ \frac{1}{2} h r \frac{a}{2} ⟶ \frac{1}{2} h r \frac{a}{4} ⟶ \frac{1}{2} h r \frac{a}{8}$

$\Rightarrow 1^{st}$ order reaction.
