The key differences between the E2 and E1 mechanism are: 1) E2 is a concerted mechanism where all the bonds are broken and formed in a single step. The E1, on the other hand, is a stepwise mechanism. ... 3) E2 is a second order reaction and the rate depends on the concentration of both, the substrate and the base.

Expert Reply: Load range D has a capacity of 1,220 lbs at 65 psi, whereas load range E has a capacity of 1,520 lbs at 80 psi. Basically the only difference between the two is the weight capacity.

The main difference between a 1st and a 2nd generation unit is the addition of a micro-channel plate, commonly referred to as a MCP. The MCP works as an electron amplifier and is placed directly behind the photocathode. ... Each tube has a micro channel plate, multi-alkaline photocathode with built-in power supply.

During this phase, the rate of formation of [ES] (one second order kinetic step) equals its rate of consumption (two first order kinetic steps). According to model (1), Rate of formation of [ES] = k1[E][S].

The difference between machine and mechanism is that machines transform energy to do work, while mechanisms so not necessarily perform this function. The term machinery generally means machines and mechanisms.

The difference between Type 1 and Type 2 Coordination Type 1 and Type 2 coordination is a definition that applies to motor starters, set out in the IEC standard 60947-4-1. The coordination level relates to the level of resilience and protection in the event of a high current short-circuit fault.

Diffusion is faster at higher temperatures because the gas molecules have greater kinetic energy. Effusion refers to the movement of gas particles through a small hole.

Generally bulky bases act in E2 reactions. They are electron rich but their really large size restricts them from acting as nucleophiles for steric reasons. ... Primary alkyl halides-always do only SN2 or E2. With a small base or nucleophile like ethoxide,SN2 will always be preferred as elimination is slowest in primaries.

Or to put it another way, EM works to improve the business while IE is concerned with the design and improvement of a system. ... Additionally, while the two areas seem to have similar courses covering quality, design, and operation, the EM courses focus more on management while the IE courses focus more on field work.

An Sn2 and Sn1 reaction mechanism. Sn2 reactions are bimolecular in rate of reaction and have a concerted mechanism. ... On the other hand, Sn1 reactions are unimolecular in rate of reaction and have a step-wise mechanism. This process first involves bond cleavage by the LG to generate a carbocation intermediate.

FADH2 produces 2 ATP during the ETC because it gives up its electron to Complex II, bypassing Complex I. By bypassing Complex I, we missed a chance to pump protons across the membrane, so less protons have been pumped by the time we get to Complex IV.

While H2 Economics covers Market Structure, H1 Economics does not. Another difference is the format of the papers. H2 Economics has Paper 1 (2 cases) and Paper 2 (3 essays), while H1 Economics only has one paper (2 cases plus 1 essays);

What is the difference in the manipulations between series 1 and series 2? 4.) In Series 1, the respiratory system compensates for acidosis whereas in Series 2 the ventilator prevents compensation. ... The respiratory rate is increased, which causes respiratory alkalosis.

The first and the main difference between both models is a built-in battery which comes in the S1 model while S2 doesn't have any battery capability. So the S1 model is more portable than S2 Spectra breast pumps and you don't want power outlet so you can pump everywhere you need.

What is the difference between condition type EK01 and EK02 in SAP SD ? EK01 is used as actual cost and EK02 is used as calculated cost. Both are used in make-to-order production. In the case of EK01, unit cost is issued first position on the conditions screen for the items.

The main difference between single- and two-stage triggers at that point is if you release a two-stage trigger without firing, the return or trigger spring will push it forward, back through the first stage. So when you fire later, you will pull through that first stage again.

So if you see a nucleophile like NaCl, NaBr, KCN, and so on, it will favor SN2 over E2. ... In contrast, the bulky base below (tert-butoxide ion) is a strong base but a poor nucleophile due to its great steric hindrance, so an E2 reaction is much more likely than SN2.
