Consider the reaction:
2N2O (g) = 2N2 (g) + O2 (g)
A. Express the rate of the reaction with respect to each of the reactants and products.
B. 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. What is the average rate of the reaction over this time interval.
C. Predict the rate of change in the concentration of N2O over this time interval. In other words, what is [N2O]/t?
