Chemistry - Chemical Kinetics Question with Solution | TestHub

Ans : (1)

$\begin{array}{rlr}& \frac{1}{C_t}-\frac{1}{C_0}=kt& \end{array}$

$\frac{C_0-C_t}{C_t}=C_{0}kt$

${\mathrm{C}}_0\mathrm{k}=\tan 45$

${\mathrm{C}}_0\mathrm{k}=1$

$\frac{2}{{\mathrm{C}}_0}-\frac{1}{{\mathrm{C}}_0}={\mathrm{kt}}_{\frac{1}{2}}$

$\frac{1}{{\mathrm{C}}_0}={\mathrm{kt}}_{\frac{1}{2}}\Rightarrow {\mathrm{t}}_{\frac{1}{2}}=\frac{1}{{\mathrm{kC}}_0}$

${\mathrm{t}}_{\frac{1}{2}}=1\min$
