In a study of the rearrangement of cyclopropane to propene at 500 °C (CH2)3 CH3CH=CH2 the concentration of (CH2)3 was followed as a function of time. It was found that a graph of In[(CH2)3] versus time in seconds gave a straight line with a slope of -1.02×10-3 sl and a y-intercept of -2.77 Based on this plot, the reaction is v order in (CH2)3 and the rate constant for the reaction is s-1 zero first Submit Answer Try Another V second item attempts remaining

Based on the answer to my question my follow-up question refers to processing. How does hydrogen bonding interactions affect the processing temperatures of these polymers? And what would we expect to occur? Why does hydrogen bonding affect thermal stabiltiy (thermo-oxidative stability) and affect degradation of the macromolecule. What is the mechanism of this interaction?

3.) State whether each statement is true or false: (a) Metals have large thermal conductivities because they expand when heated.   (b) Metals have large thermal conductivities because the delocalized electrons can easily transfer the kinetic energy imparted to the metal from heat.  Group of answer choices A. a) false b) true B. a) true b) false C. (a) true (b) true D. (a) false (b) false

Consider each of the following monomers and predict if it would likely undergo radical, anionic, or cationic addition polymerisation. Then, in the space provided below, draw the electron pushing mechanism for the initiation and the first propagation steps of the monomer that you chose for each (the catalyst is provided for you). Then draw what the growing polymer chain looks like and briefly indicate why you chose that monomer to undergo the selected type of polymerisation (hint: consider concepts such as electron donating group, electron withdrawing group, resonance, and hyperconjugation!)

I need more reasons why it's no longer used.

The number-average degree of polymerization is given by n = M₂m, where mis the molecular weight of the monomeric unit. For the above sample n corresponds to the value 785. Determine which of the following polymers is present in the sample (all calculations must be shown). H I 11 Dt. Ht. CI A B D

Which of the following provides an absolute measure of the molecular weight of polymers:(a) viscometry, (b) cryometry, (c) osmometry, (d) light-scattering photometry, (e) GCP?
