WitrynaSo, the rate constant k for a first order reaction. rate = k [A] 1. k = rate/ [A] 1. therefore units of k = mol dm -3 s -1 /mol dm -3 = s -1. For a second order reaction. rate = k [A] 2. k = rate/ [A] 2. therefore units of k = mol dm -3 s -1 /mol 2 dm -6 = dm 3 mol -1 s -1. Note that the above refers to the overall order of the rate equation ... Witryna14 sty 2024 · Well, it may not be appropriate to say that the rate constant, k, has no physical meaning. It is the only factor in the rate equation which is temperature …
For a reaction of order n, the unit of the rate constant is ...
Witryna12 lut 2024 · Solution. Because the rate is first-order in bromate, doubling its concentration doubles the reaction rate. Increasing the pH by one unit decreases the [H +] by a factor of 10.Because the reaction is second-order in [H +], this decreases the rate by a factor of 100.; Dilution reduces the concentrations of both Br 2 and BrO 3 – to … Witryna28 lut 2024 · Explanation: From the rate equation we can see,the reaction is a first order reaction,as it depends on the 1 degree power of the conc. of X, So, unit of k will be 1 … michelin scorpion tyres
