in the first order reaction A yields to products. [A]=0.816 M initially and 0.632M after 16.0 min.
a. what is the value of the rate concentration. k?
b. what is the half-life of this reaction?
c. at what time will [A] = 0.235M?
d. what will [A] be after 2.5 h?

To date the Charcoal found at an archeological site, this sequence of experiments was done. The Charcoal Sample was burned in oxygen and the CO2 obtained was captured by bubbling through lime water, Ca(OH)2, to perform a precipitate CACO3. The precipitate was filtered, dried and weighed. A sample of

A solution of permanganate was added to an acidified solution ofoxalate and resulted in decolorization of the purple permanganate.The rate of this reaction as well as its energy of activation wasstudied based on this disappearance. Given 50 mL of 0.1 M permanganate (KMnO4) and 10.0 mL of 0.

A cache of Hebrew manuscripts known as Dead Sea Scrolls was found in 1947. The activity of Carbon-14 in the linen wrappings of the Book of Isaiah was about 14 disintegration per minute per gram (d/ min*g). Calculate the approximate age of the linen.Given:t1/2 of Carbon-14 is 5.73*10^3 yearsthe beta

I need help answering questions to this assignment and how the answers can be worked out.

A reaction has a rate constant of 1.2110-4 /s at 29 degrees C and 0.226 /s at 76 degrees C.a)Determine the activation barrier for the reaction.b)What is the value of the rate constant at 15 degrees C?

For the reaction 2 N2O5(g) > 4 NO2(g) + O2(g)What is the average rate of reaction when N2O5 is being used up at a rate of 0.086 M/s?

The following reaction was monitored as a function of time: A-> B + CA plot of ln[A] versus time yields a straight line with slope -4.510^-3/s.If the initial concentration of A is 0.290 M, what is the concentration after 210 s?

The reaction
2NO(g) + Cl2(g) >2NOCl(g)

The reaction between chlorine and dissolved liquid toluene at 170 degrees Celcius is catalyzed by acids. With a catalyst concentration equal to 0.117 mol / L, the reaction was monitored by analyzing the chlorine:
(t/min -1) 0 3 6 10 14
10^2 Cl2/ (mol/L) 7,75 5,65 4,10 2,65 1,75
Demonstrate that it is a first order reaction.
