- An elementary reaction is generally expressed as: dC :-kC," dt where A is the species being depleted as the reaction progresses, k is the rate constant, and n is the order of reaction, usually referred to as the stoichiometric coefficient of the resulting product. For a polymerization reaction A> 3B, find the initial amount if after 30 seconds, A species is reduced to 5 moles/L within 3 minutes. Take the rate constant as 0.314 L?/(molľ²-min).An elementary reaction is generally expressed as: dC, = -kC," dt where A is the species being depleted as the reaction progresses, k is the rate constant, and n is the order of reaction, usually referred to as the stoichiometric coefficient of the resulting product.

Take the rate constant as 0.314 L'/(moP-min).Living chain polymerization of monomer X follows the first-order kinetics.

Export the graph in TIFF format and paste it below as an image. Make sure the graph is graphically appealing! b) From this fitting, calculate the kp of polymerization, assuming the living character of polymerization and an initial initiator concentration (an thus the constant concentration of growing centers) of 0.09 M c) What is the theoretical degree of polymerization (DP) of the prepared polymer?

- Rate law experiments don’t always give data in the form of a rate in molesper second. Some of them give an amount of time necessary for areaction to proceed to a given point. The faster the rate, the less timenecessary. For the following data, assume that the time recorded for eachexperiment is the time required to consume 0.10 M of A in a hypotheticalreaction A + B yields C Time taken (s) [A]0 [B]0 36.8 0.20 0.40 25.0 0.20 0.60 10.0 0.50 0.60 Determine the rate law and the rate constant for the reactionCalculate the velocity of the reaction (M · s–1) of an α-amino group in a blood protein at 37°C if its concentration is 0.60 mM and the partial pressure of carbon dioxide is 40 torr. Use 2 significant figures and scientific notation (example: 1000 would be entered as 1.0e+3). The rate constant k for this reaction is 4950 M–1·s–1.Static fatigue depends on a chemical reaction and, as a result, is another example of Arrhenius behavior. Specifically, at a given load, the inverse of time to fracture has been shown to increase exponentially with temperature. The activation energy associated with chemical reaction is 78.6 kJ>mol. If the time to fracture for a soda–lime–silica glass is 1 second at +50°C at a given load, what is the time in hours to fracture at -50°C at the same load?
