Problem: Consider the following reaction: 2 N2O(g) → 2 N2(g) + O2(g). In the first 15.0 s of the reaction, 0.015 mol of O2 is produced in a reaction vessel with a volume of 0.500 L. Predict the rate of change in the concentration of N2O over this time interval. In other words, what is Δ[N2O]/Δt?large{frac {Delta [ m N_2O]}{Delta t}}

🤓 Based on our data, we think this question is relevant for Professor Tyson's class at UMASS.

FREE Expert Solution

(1) The rate of a chemical reaction can be written in terms of the change of concentration of reactants and products.

Rate = -[reactants]at = +[products]bt

The rate of reaction in terms of O2 is:

Rate = +[O2]t


The rate of reaction in terms of N2O is:

Rate = -[N2O]2t
