You need a graphic concentration versus absorbance.
the experimental rate law of a simple reaction A->B+C is v=k[A].calculate the change in the reaction rate when:(a) the concentration of A is tripled (b) the concen-tration of A is halved
The equation for fermentation of the simple sugars to alcohol are, Sugar (glucose) yields alcohol (Ethyl alcohol) + CO2 (g) + energy.
We would need to know the path length and the molar extinction coefficient to answer that question. If you know these, it's an extremely simple matter of Beer's Law and algebra.
The movement of molecules from an area of high concentration of that molecule to an area of lower concentration is called simple diffusion.
No, simple diffusion is not saturable because it does not involve specific carrier proteins or channels that can become saturated as concentration increases. Instead, it is a passive process that relies on the concentration gradient of molecules for movement across a membrane.
Simple. Because you have the percent transmittance (%T).Instead of using the Beer-Lambert Law:A=ϵbcyou use equation 7:A=2.00−log(%T)
The only way to do it, professionally, is DSC (Differential Scanning Calorimetry) But what most of everybody does is a lot more simple. Put a handful of PET flakes in an aluminum tray, put it in your kitchen oven (when your wife is not around) heat it up at 210° C for 20 minutes. If you see black spots this is PVC. If flakes only turn yellow, you still have glue. If flakes remain clear you are in very good shape.
The Griess assay is a simple colorimetric method used to quantify the levels of nitric oxide (NO) in a sample. In this method, nitrate and nitrite are first converted to nitrite by a nitrate reductase enzyme. The nitrite is then reacted with a Griess reagent to form a purple compound whose absorbance is measured at 540 nm. This absorbance is directly proportional to the concentration of NO in the sample.

Simple equation: ECD, ppg = [ (annular pressure, loss, psi ) ÷ (0.052 x TVD, ft) ] + (mud weight, in use, ppg)
you find the hard equation and simplify it....
High temperatures can lead to increased molecular vibrations and transitions to higher energy states, resulting in higher absorbance. Ethanol, being a relatively simple molecule, may not exhibit as strong absorption characteristics compared to more complex molecules or at higher temperatures. The combination of temperature and molecular structure can affect the absorbance of a substance.
I'm doing this lab, and it was explained to me by my instructor... Basically, on the x-axis you'll have the concentration of a substance, and on the y-axis you'll have the %T, or A, the absorbance of the substance when it's put into a spectrophotometer. so you plot the points, get a line of best fit (this is your calibration curve), and then basically you use that line to get the concentration of the substance, when you've already calculated the A. . And from that concentration, you can extrapolate the concentration of the reactants/products (Depending on what you're looking for) to find the equilibrium constant. Here's an example: iron and thiocyanate ions bond to form iron thiocyanate in the following equation: Fe(3+) + SCN(-) --> FeNCS(2+) For the experiment I did, a calibration curve was made with reacted Fe(3+) and SCN(-). So for my calibration curve, I got the concentration of FeNCS(2+) on the x-axis, and the absorbance or A on the y-axis. So you basically got to find the equilibrium concentrations of the Fe(3+) and the SCN(-), cuz you've already got the equilibrium concentration for FeNCS(2+). So you start with the initial, use the equilibrium FeNCS(2+) to calculate the equilibrium concentration of the reactants. Here's the equation: equilibrium [Fe(3+)] = initial [Fe(3+)] - equilibrium [FeNCS(2+)]. And the same goes for the SCN ion.. you just switch out the numbers. So now that you got all that, it's simply a matter of dividing the product concentrations by the multiplication of the reactant concentrations. and boom, you have found the equilibrium constant. Keep it simple stupid, y'all. There is another way to find it, and that's using the Beer-Lambert's law..
Simple form is where all of the variables in the equation are put on one side on the equation, which a zero on opposite side of the equation ex. a+b+c=0 18a + 4b + 5 = 0
simplify. Can you simplify this equation?

Yes, simple diffusion/passive diffusion is the movement of a particle from an area of high concentration to one of lower concentration.
