In specified conditions the rate of consumption of N205 in the reaction 2N2O5 4NO2 + 02 is 0.5 mol N2O5 LS The rate of formation of NO2 isRATE
Correct answer: D. 1
- A. 0.5
- B. 4
- C. 2
- D. 1
Explanation
In the balanced chemical equation: 2N2O5 4NO2 + O2.The stoichiometric coefficient of N205 is 2, and the stoichiometric coefficient of NO2 is 4.Given that the rate of consumption of N205 is 0.5 mol N2O5 L¹¹ we can use the -1 stoichiometry of the reaction to find the rate of formation of NO2.Since 2 moles of N205 produce 4 moles of NO2, the rate of formation of NO2 will be twice the rate of consumption of N205.Therefore, the rate of formation of NO2 is 2 x 0.5 = 1 mol NO2 L¹ sSo, the correct answer is:d.1

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
