Discussion: What is the significance of the value n,of the reaction order in chemical kinetics? Derive the integrat...
Derive the integrated law for zero and second order kinetics.
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...

Question text The following chemical reaction: A → products shows first order kinetics with respect to A; rate = k[A]. If k = 6.80 x 10-5 s-1 and the initial concentration of A is 0.63 mol L-1, what is the half life of this reaction in hours?
help please The following chemical reaction: A → products shows second order kinetics with respect to A; rate k[A2 Assume k = 11.88 x 10-5 mol-1 L s-1 If the initial concentration of A is 0.28 mol L-1, what is the concentration of A in mol L-1) after 3.03 hours? You have 5 attempts at this question. Remember: if you want to express an answer in scientific notation, use the letter "E". For example "4.32 x 101" should be entered...
The kinetics of the rvaction between NO and H2 was fully studied First the order of the reaction with respect to I112] was determined using the inital rate method- Question 19 Second, the order of the reaction with respect ot [NOI was determined using the graphs of the integrated rate equations Question 20 Thied, a mechanism was peuposed, and must be validated -Question 21. Fourth, Write the rate law- Question 22 19) The fellowing data were oblained for [H21 when...
Post Lab Question for Kinetics 1. The rate of decomposition of azomethane (C2HsN2) is studied by monitoring the partial pressure of the reactant as a function of time: CH3-N-N-CH3(g) -N2(g) + C2Hsg) The data obtained at 300 °C are listed in the following table: Time (s) 0 100 150 200 250 300 Pazomethane (mmHg) 284 220 193 170 150 132 Using Excel create Pc2HGN2 vs. t, In(Pc2H6N2) vs. t, and 1/Pc2H6N2 vs. t plot that should include linear regression trend...
