Chemistry - Chemical Kinetics Question with Solution | TestHub

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,$\text{k}\text{=}\text{4}\text{.606}\text{×}{\text{10}}^{-\text{3}}{\text{sec}}^{-\text{1}}\text{,}\text{log}\text{2}\text{=}\text{0}\text{.3}$)
