The rate of reaction can be expressed as:
Δ[O2]

Δt
List two other ways to represent the rate of this reaction.
You need to tell us the reaction.
2N2O5 ==> 4NO2 + O2
To express the rate of a reaction, there are two other commonly used ways:
1. Rate of consumption or production of reactants/products: This representation focuses on the change in concentration or amount of the reactants or products per unit time. For example, if we consider the reaction 2H2 + O2 → 2H2O, we can express the rate as:
- Δ[H2] / Δt: Rate of consumption of H2
- Δ[O2] / Δt: Rate of consumption of O2
- Δ[H2O] / Δt: Rate of production of H2O
2. Stoichiometric coefficients: Another way to represent the rate of a reaction is by considering the stoichiometric coefficients of the reactants and products. The stoichiometric coefficients indicate the ratio in which the reactants combine or the products are formed. In the case of the reaction 2H2 + O2 → 2H2O, the reaction rate can be expressed as:
- (-1/2) Δ[H2] / Δt: Rate of consumption of H2
- (-1/2) Δ[O2] / Δt: Rate of consumption of O2
- Δ[H2O] / Δt: Rate of production of H2O
In both cases, the rate is determined by measuring the change in concentration or amount of the involved species (reactants or products) over a specific time interval (Δt).
