Question

Express the average rate of following reaction in terms of concentrations of reactants and products:

\[\ce{2NO2 + F2 -> 2NO2F}\]

Answer 1

For the reaction \[\ce{2NO2 + F2 -> 2NO2F}\]

The average rate of reaction is expressed as the change in concentration of reactants or products per unit time, adjusted by their stoichiometric coefficients.

Rate = \[\ce{\frac{1}{2}\frac{d[NO_{2}]}{dt}}\]

= \[\ce{- \frac{d[F_{2}]}{dt}}\]

= \[\ce{\frac{1}{2}\frac{d{[NO_{2}F]}}{dt}}\]
