For the decomposition of dinitrogen pentoxide in carbon tetrachloride solution at 30 °C 2 N2O54 NO2 + O2 the average rate of dis
geniusboy [140]

The average rate of formation of O2 is 4.225 × 10-4 M min-1

<h3>What is the equation of the reaction?</h3>

The equation of the reaction is given below:

  • 2 N2O54 ----> NO2 + O2

From the equation of the reaction, 2 moles of Ibuprofen pentoxide decomposes to produce 1 mole of oxygen.

<h3>What is the average rate of formation of 02?</h3>

Rate of reaction is given as:

  • Moles of product formed/moles of reactants used up/ time
  • The ratio of mole of dinitrogen pentoxide decomposed to moles of oxygen produced is 2:1

Rate of disappearance of N2O5 = 8.45×10-4 M min-1.

Therefore, average rate of formation of O2 = 1/2 × 8.45×10-4 M min-1

Average rate of formation of O2 = 4.225 × 10-4 M min-1

Therefore, the average rate of formation of O2 is 4.225 × 10-4 M min-1
