For a type 2 second order reaction, the reaction is 60% complete in [A] in 60 seconds when [A]0 = 0.1 M and [B]0 = 0.5 M. What is the rate constant for this reaction? Calculate the time for the reaction to reach 60% completion change if the initial reactant concentrations are decreased by a factor of 2. (Are the two times the same regardless of initial reactant concentrations?)

The second order gas phase irreversible reaction: 2.4-B is carried out in an isothermal batch reactor containing 40 kg of catalyst and with an initial volume of 60-liter. The reactor is initially filled with equal molar quantities of A and inert I at 300 K and 2.5 atm.

An acid-catalyzed irreversible liquid-phase reaction A B is carried out adiabatically in a CSTR. The reaction is second order in A. The feed is equimolar A and solvent (S, which contains catalyst), and enters the reactor at a total volumetric flow rate of 10 dm3/min at a concentration of A of 4 mol/L. The feed enters at 300 K. The product and reactant heat capacities are 15 cal/(mol°C), the solvent is 18 cal/(mol°C). The reaction rate constant at 300 K...

+ Half-life for First and Second Order Reactions 11 of 11 The half-life of a reaction, t1/2, is the time it takes for the reactant concentration A to decrease by half. For example, after one half-Me the concentration falls from the initial concentration (Alo to A\o/2, after a second half-life to Alo/4 after a third half-life to A./8, and so on. on Review Constants Periodic Table 11/25 For a second-order reaction, the half-life depends on the rate constant and the...

For a first-order reaction, the half-life is constant. It depends only on the rate constant k k and not on the reactant concentration. It is expressed as t1/2=0.693k t 1 / 2 = 0.693 k For a second-order reaction, the half-life depends on the rate constant and the concentration of the reactant and so is expressed as t1/2=1k[A]0. A certain first-order reaction (A→products A → p r o d u c t s ) has a rate constant of 9.30×10−3...
