Arrhenius defines an acid as

Consider the following hypothetical aqueous reaction: A(aq) → B(aq). A flask is charged with 0.065 mol of A in a total volume of 100.0 mL. The following data are collected. Calculate the average rate of appearance for B in units of M/s between 20 and 40 minutes. Time (min) 0 10 20 30 40 Moles of A 0.065 0.051 0.042 0.036 0.031

The decomposition reaction of N2O5 in carbon tetrachloride is 2 N2O5 → 4 NO2 + O2. The rate law is first order in N2O5. At 64 °C the rate constant is 4.82 × 10–3 s–1. What is the rate of reaction when [N2O5] = 0.0240 M?

A reaction involves 2 different reactants and both reactants are first order. How does the rate change if the concentration of both reactants is doubled?

A reaction A + B → C obeys the following rate law: Rate = k [A][B]2. What are the reaction orders for A and B and the overall reaction order?
