🤓 Based on our data, we think this question is relevant for Professor Driessen's class at UMN.
Recall that for a reaction aA → bB, the rate of a reaction is given by:
Δ[A] = change in concentration of reactants or products (in mol/L or M), [A]final – [A]initial
Δt = change in time, tfinal – tinitial
The decomposition of NOBr is studied manometrically because the number of moles of gas changes; it cannot be studied colorimetrically because both NOBr and Br2 are reddish brown:
2NOBr(g) ⟶2NO(g) + Br2(g)
Use the data below to answer the following:
(a) Determine the average rate over the entire experiment.
