Description: At a certain moment in the reaction, 2 N2 O5 ⟶4 NO2+O2 N2 O5, is decomposing at a rate of 2.5 ×10^-6 mol L^-1 s^-1. What are the rates of formation of NO2 and O2 ?

step 1 So here we're given a chemical reaction where nitrogen pentoxide decomposes to nitrogen dioxide

Question

At a certain moment in the reaction, $$2 \mathrm{~N}_{2} \mathrm{O}_{5} \longrightarrow 4 \mathrm{NO}_{2}+\mathrm{O}_{2}$$ $\mathrm{N}_{2} \mathrm{O}_{5}$, is decomposing at a rate of $2.5 \times 10^{-6} \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~s}^{-1}$. What are the rates of formation of $\mathrm{NO}_{2}$ and $\mathrm{O}_{2}$ ?

   At a certain moment in the reaction, $$2 \mathrm{~N}_{2} \mathrm{O}_{5} \longrightarrow 4 \mathrm{NO}_{2}+\mathrm{O}_{2}$$
$\mathrm{N}_{2} \mathrm{O}_{5}$, is decomposing at a rate of $2.5 \times 10^{-6} \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~s}^{-1}$.
What are the rates of formation of $\mathrm{NO}_{2}$ and $\mathrm{O}_{2}$ ?

Key Concepts

Stoichiometric Rate Relationships

Using the stoichiometric coefficients from the balanced equation, the rate of reaction for reactants and products can be related mathematically. Multiplying the rate of one species by the ratio of the respective coefficients allows calculation of the rates of other species, thereby linking the consumption and formation processes in a consistent manner.

Reaction Rate

The reaction rate quantifies the speed at which reactants are consumed or products are produced in a chemical reaction, typically expressed as the change in concentration per unit time. It is a fundamental concept that characterizes the dynamics of chemical processes.

Reaction Stoichiometry

This concept involves the use of a balanced chemical equation to relate the amounts of reactants consumed and products formed. It highlights how the stoichiometric coefficients indicate the proportional relationships between moles of different species in a reaction.
