1-The rate constant of a chemical reaction was measured at several temperature values and a plot of ln k (on the y-axis) was plotted against 1/T (on the x-axis, temperature was measured in Kelvin). If the slope of the plot was -9.21 x 103 K and the y-intercept was 13.0, what is the activation energy (EA) of the reaction in kJ mol-1? 2-In an enzyme-catalyzed reaction, the rate of the reaction depends on which of the following at very low...

Compare and contrast how first-order reaction kinetics and zero-order reaction kinetics differ in terms of the depletion of a reactant A in a chemical reaction. Assume an initial concentration of 420 mg of A. Assume a half-life of 30 minutes if first-order kinetics are obeyed, and a depletion rate of 60 mg/hour if zero-order kinetics are obeyed. Use a clearly drawn graph(s) to determine which rate will result in complete depletion of A over the shortest time. Assume 99% to...
