The second-order rate constant for the decomposition of nitrous oxide (N2O) into a nitrogen molecule and oxygen atom has been measured at different temperatures given below.
k(1/M·s) t(°C)1.87 multiplied by 10-3 6000.0113 6500.0569 7000.244 750
Determine graphically the activation energy for the reaction
The heat of vaporization of water at this temperature is 574 cal/g. We normally do not sweat this much. Explain what is wrong with this calculation?
If the imaging agent had an initial rate of 7500 decays per minute (dpm) and if the imagine required 1 hour to complete, what would the decay rate be immediately after the test is completed?
Radiation therapy. An effective treatment for some can cancerous tumors involve irradiation with fast neutrons. The neutrons from one treatment source have an average velocity of 3.2 X10-7 m/s.
A sample of a liquid from an unlabeled bottle was subjected for analysis: MS showed that M+ has an m/z of 89 and IR displayed bands at 2995-2840 cm-1, and 1562, and 1425. Identify the functional group in the molecule and provide 2 possible structu..
the vapor pressure of pure A and pure B are 76.5 kPa and 48.2 kPa respectively. When the total vapor pressure is .593 atm, calculate the mole fraction of A and B in the liquid mixture
-13 degrees C air pressure in an auto tire is 1.5 atm. if the volume does not change, what is the pressure after the tire has warmed to 15 degrees C?
A voltaic cell is constructed by immersing a strip of silver metal in a 1.0 M AgNO3 solution and a strip of lean in 1.0 M Pb(NO3)2 solution. A wire and salt bridge complete the cell. What is the potential for the cell
These compartments are connected by a partition that transmits heat. What is the final temperature in the box at thermal equilibrium
The following set of data was obtained by the method of initial rates for the reaction: S2O8^2- (aq) + 3 I- (aq) ==> 2 SO4^2- (aq) + I3- (aq) What is the initial rate when S2O8^2- is 0.15M
In S8 + 12O2-> 8SO3, if 10 grams of sulfur is used, how many grams of sulfur trioxide are produced?
What ions and/or molecules are present in relatively large proportions in a solution of the soluble ionic compound KCl (aq)?
A particulate water sample that is saturated in CaF2 has a Ca2+ content of 105 ppm (that is, 105 g Ca2+ per 10^6 g of water sample).
