At $500 K$ , the half life period of a gaseous reaction at an initial pressure of $80 k P a$ is $350 s$ . When the pressure is $40 k P a$ , the half life period is $175 s e c$ ; the order of the reaction is :

Options:

Answer:

Solution:

$\begin{array}{l} (\frac{T_{\frac{1}{2}}}{T_{\frac{1}{2}}}) = {(\frac{C_{1}}{C_{2}})}^{1 - n} \\ \Rightarrow (\frac{350}{175}) = {(\frac{80}{40})}^{1 - n} \\ = 2 = {(2)}^{1 - n} \Rightarrow 1 - n = 1 \\ \Rightarrow n = 0 \end{array}$
