Consider the following reaction: $2 NO_{2(g)} + F_{2(g)} \longrightarrow 2 NO_2F_{(g)}$. The expression for the rate of reaction in terms of the rate of change of partial pressure of reactant and product is/are:
- Arate $= -\frac{1}{2} \left[ \frac{dp(NO_2)}{dt} \right]$
- Brate $= \frac{1}{2} \left[ \frac{dp(NO_2)}{dt} \right]$
- Crate $= -\frac{1}{2} \left[ \frac{dp(NO_2F)}{dt} \right]$
- Drate $= \frac{1}{2} \left[ \frac{dp(NO_2F)}{dt} \right]$
