3. The following table shows how the concentration of AB varies in the reaction: 2 AB(g) → A2(g) +B2(g). Time (s) 0 1000 2000 3000 4000 [AB] (mol/L) 1.00 0.112 0.061 0.041 0.031 Determine: a) The global reaction order. b) The kinetic constant for the rate of disappearance of AB. c) The kinetic constant for the rate law (independent of the reactant). Use trial end error using excel.

The reaction below was monitored as a function of time: AB A + B A plot of ln[AB] vs. time yields a straight line with slope = -0.0025 sec-1 . a) What is the value of the rate constant (k) for this reaction at this temperature? b) Write the rate law for this reaction. c) What is the half-life (t1/2)? d) If the initial concentration of AB is 0.500 M, what is the concentration after 300 sec?
Consider the first order reaction, AB2 -> AB + B, which has a first order reaction rate constant of 0.00920 s'. If[AB2] = 0.0100 M at the beginning of the reaction, how many seconds will it take for the concentration to drop to 0.00250 M? a) 151 s b) 75.5 s c) 38.0 s d) 302 s Оа Ob Ос C
A + B -> C : Derive the rate law for the reaction based on the following information. What would happen if I double the concentration of A and double the concentration of B, the reaction rate increase 32 times. How about if I triple the concentration of A and keep the concentration of B the same, the reaction process 9 times faster.
Question 2 If the rate does not change when we double the concentration, therefore, the reaction is: a. Individual order b. First order C. Zero order d. Second order
Review | Constants Periodic Table Leaming Goal: To understand reaction order and rate constants. For the general equation A+B+C+ dD. the rate law is expressed as follows: ratek AB" where mand n indicate the order of the reaction with respect to each reactant and must be determined experimentally and kis the rate constant, which is specific to each reaction Order For a particular reaction, aA +bB+CD the rate law was experimentally determined to be rate - KABC -- EBC2 A....
(a)The reaction A(aq) → B(aq) is a first order reaction with respect to A(aq). The concentration of A(aq) after 100.0 seconds of reaction is 0.970 M and the concentration of A(aq) after 400.0 seconds of reaction is 0.715 M. What will be the concentration of A(aq) after 817.6 seconds of reaction? (b) The reaction A(aq) → B(aq) + C(aq) is a first order reaction with respect to A(aq). The half-life of A(aq) is 81.8 s at 25.0oC. Its activation energy...
