Which of the following represents integrated rate law equation for gas phase first order reaction, $$\mathrm{A}_{(\mathrm{g})} \rightarrow \mathrm{B}_{(\mathrm{g})}+\mathrm{C}_{(\mathrm{g})}$$

if $$\mathrm{P}_{\mathrm{i}}=$$ initial pressure of $$\mathrm{A}$$

$$\quad\mathrm{P}=$$ total pressure of reaction mixture at time ?

$$ \mathrm{k}=2.303 \times \log _{10} \frac{\mathrm{P}_{\mathrm{i}}}{2 \mathrm{P}_{\mathrm{i}}-\mathrm{P}} $$

$$ \mathrm{k}=\frac{2.303}{\mathrm{t}} \times \log _{10} \frac{\mathrm{P}_{\mathrm{i}}}{2 \mathrm{P}_{\mathrm{i}}-\mathrm{P}} $$

$$ \mathrm{k}=\frac{1}{\mathrm{t}} \ln \frac{2 \mathrm{P}_{\mathrm{i}}-\mathrm{P}}{\mathrm{P}_{\mathrm{i}}} $$

$$\mathrm{k=\frac{2.303}{t} \times \log _{10} \frac{P_i-P}{P_i}}$$
