Consider the following gaseous reaction where initial pressure of $\text{A(g)}$ is $\text{200}\text{torr}$
$\text{A(g)}\to \text{3B(g)}\text{+}\text{C(g)}$
After time $\text{t,}$ the pressure of system increased to $\text{650}\text{torr}\text{.}$ Calculate the value of $\text{t}$ (in seconds)
(Given: rate constant of reaction, $\text{k}\text{=}\text{4}\text{.606}\text{×}{\text{10}}^{-\text{3}}{\text{sec}}^{-\text{1}}\text{,}\text{log}\text{2}\text{=}\text{0}\text{.3}$)
