reactionratechemicalkinetics化学反应动力学 The Rate of a Chemical Reaction: Chemical Kinetics A.P. Chemistry Purpose: To determine the rate law for the reaction: H2O2 + 2I- + 2H+ I2 + 2H2O The rate law will take the form: Rate = k[H2O2][I-][H+] Background: Two important questions...
\(rate=k[3]^x[1]^y\) and \(rate=k[3]^x[2]^y\) The ratio between the two right hand sides of the equation is 4, so after dividing the first equation by the second, you get: \(4 = 2^y\) So y = 2. Next, you can find the order with respect to H2. Experiments 2 an...
In this paper we deduce the formulae for rate-constant of microreaction with high resolving power of energy from the time-dependent Schrdinger equation for the general case when there is a depression on the reaetional potential surface (when the depression is zero in depth, the case is ...
The rate constant, k, is dependent on the temperature, fraction of reactant molecules having translational energy greater or equal to the activation energy barrier, and the reactant collisional cross section. The Arrhenius equation fully describes this relationship: (9)k=Aρe−EaRT where ρ is...

The ability to capture the influence of local transport effects and reactor flow pattern on the reactor-averaged apparent reaction rate is necessary to accurately determine the volumetric productivity and selectivity of...
Therate constant, or the specific rate constant, is the proportionality constant in the equation that expresses the relationship between the rate of a chemical reaction and the concentrations of the reacting substances.
