Q. Consider the following reaction for $2NO_{2(g)} + F_{2(g)} → 2NO_{2F(g)}$. The expression for the rate of reaction interms of the rate of change of partial pressures of reactant and product is/are

WBJEEWBJEE 2013Chemical Kinetics

Solution:

$2 NO _{2}(g)+ F _{2}(g) \longrightarrow 2 NO _{2} F (g) $
Rate of reaction $=-\frac{1}{2}\left[\frac{d p\left( NO _{2}\right)}{d t}\right] $
$=-\left[\frac{d p\left(F_{2}\right)}{d t}\right] $
$=+\frac{1}{2}\left[\frac{d p\left( NO _{2} F \right)}{d t}\right] $
