For each problem, write the relevant design equation and plot all relevant concentration profiles (from t=0 until steady state) for the specific batch reactions. All reactions are constant temperature and constant volume. If initial concentrations are not given in the problem, they are equal to zero.

2nd order, irreversible (r = kCA2) reaction. CA0 = 5 mol/L, k = 0.25 min-1. 2nd order, irreversible (r = kCACB) reaction. CA0 = 5 mol/L, CB0 = 10 mol/L, k = 0.25 min-1.
