The propagation rate increases with increasing monomer and initiator concentration.
8. Know how increasing the initiator concentration does affect the rate of polymers formed by cationic...
Polymer chemistry If an initiator has a halt-life of 4h, what percentage of this initiator will remain after 12 h? Which is the better way to increase polymer production rates for free-radical reactions in general (a) increasing temperature or (b) increasing the initiator concentration and why? What is the limiting step in free-radical chain polymerization? What is the advantage of producing free-radicals by UV radiation instead of thermal energy? If [M] = 1 Times 10^-11 mol/L under steady-state conditions, what...
Experiment 1 Experiment 2 Rate of reaction Rate of reaction Increasing concentration does not affect reaction rate Enzyme concentration Substrate Concentration What has become rate limiting in Experiment 2 at (and after) the green X?
Experiment 1 Experiment 2 Rate of reaction Rate of reaction Increasing concentration does not affect reaction rate Enzyme concentration Substrate Concentration In Experiment 1, what would happen to the slope of the line if you decreased the amount of substrate?
For polymerization of styrene in tetrahydrofuran at 25°C using sodium naphthalide initiator, the rate coefficient for propagation is 550 dm^3 mol^-1 s^-1. If the initial mass concentration of styrene is 156 g dm^-3 and that of sodium naphthalide is 3.02x10^-2 g dm^-3, calculate the initial rate of polymerization and, for complete converison of the styrene, the number-average molar mass of polystyrene formed. Comment upon the expected value of molar mass dispersity (Mw/Mn) and the stereoregularity of the polystyrene produced. Assume:...
How does increasing the capacitance affect the charge on the capacitor with a constant voltage? How does increasing the capacitance affect the voltage across the capacitor with a constant charge? How does a larger capacitance affect the glowing light bulb (in terms of its brightness and rate of dimming)
2. We can measure how fast the Product is formed at increasing levels of Substrate Concentration The rate of the reaction can be plotted below. This is called a Michaelis-Menten Graph and it shows several important features of the enzyme: a. What happens to the reaction rate as the amount of substrate is increased? reaction rate- b. Why does the graph level off at high levels of substrate concentration? substrate concentration
How does the difference in solute concentration across a membrane affect the rate of diffusion?
How does doubling the concentration of both the alkyl halide and the nucleophile affect the rate of the above S N1 reaction?
How does halving the nucleophile concentration affect the rate of an E2 reaction? Select the single best answer. o no change O rate halved O rate quadrupled o rate doubled
"How does a positive, neutral (zwitter) and negative amino acid effect a cationic surfactant?" Can someone please explain in details using Arginine, Isoleucine and Glutamic acid as explain? Also, how each can effect the Critical Micelle Concentration of a cationic surfactant? This is for my PCHEM lab btw.
