In this study, we propose a simple formula to calculate the steady-state surface averaged Sherwood number at high Schmidt numbers when a first-order chemical reaction occurs on a wall. The formula uses the surface averaged Sherwood number corresponding to the mass transfer rate with an infinitely...

Answer to: What is the rate constant of a first-order reaction that takes 536 seconds for the reactant concentration to drop to half of its initial...
Re: First order reaction, temperature and reaction rate constant? « Reply #1 on: December 16, 2007, 12:55:40 PM » Hello tammx ,Your answer is correct but dont forget to include the unit of k : 1/s. The temperature is specified because k=f(T), so the temp must be included ...
The data from Figure 1 with the addition of values of ln[H2O2] are given in Figure 2. Figure 2. The linear relationship between the ln[H2O2] and time shows that the decomposition of hydrogen peroxide is a first-order reaction. TrialTime (h)[H2O2] (M)ln[H2O2] 1 0 1.000 0.0 2 6.00...
which is related to a system of monomolecular reversible first-order reactions, Ai⇄Ai+1 with i=1,2,⋯,Nc. Every nondiagonal element of the kinetic matrix is the rate coefficient of a reaction. For example, the element (1,2) represents the rate coefficient k12 of the reaction A1→A2...
To calculate the half-life of a first-order reaction, we can use the formula: t1/2=0.693k where t1/2 is the half-life and k is the rate constant. Step 1: Identify the Rate ConstantThe given rate constant k is: k=0.0005min−1 Step 2: Substitute the Value into the Half-Life ...
