You are given that kc = 10-1 kg eq-1 min-1, ku = 10-3 kg2 eq-2 min-1 and [A]0 = 10 eq kg-1, where kc is the rate constant for a

catalyzed step-growth polymerization, ku is the rate constant for an uncatalyzed step-growth polymerization, and [A]0 is the initial concentration of monomer A in the step-growth polymerization. Assume that the stoichiometry of monomer A to monomer B is 1:1, that the reactive groups on A only react with the reactive groups on B, and that the reactivity of A and B is independent of the chain length.
A. Calculate the time in minutes for conversion (p) to reach values of 0.2, 0.4, 0.6, 0.8, and 0.99 for both catalyzed and uncatalyzed polymerizations.B. Next, calculate the number-average degree of polymerization at each of these times.C. Assume that you can recover all of the catalyst (i.e., the cost of the catalyst is not a factor), which polymerization route is more economical from an industrial perspective?

A MOSFET differs from a JFET mainly because
Solnce55 [7]

Answer:

The answer is option

C . the JFET has a PN junction

Explanation:

Not only is option C in the question a dissimilarity between the MOSFET and the JFET we can go on with some more dissimilarities.

1.MOSFET stands for Metal Oxide Silicon Field Effect Transistor or Metal          Oxide Semiconductor Field Effect Transistor.

  (JFET) stands for junction gate field-effect transistor (JFET)  

2. JFET is a three-terminal semiconductor device, whereas  MOFET a four-terminal semiconductor device.  

3. In terms of areas of application of  JFETs are used in low noise applications while MOSFETs,  are used for high noise applications

For a steel alloy it has been determined that a carburizing heat treatment of 15 h duration will raise the carbon concentration
Free_Kalibri [48]

Answer:

135 hour

Explanation:

It is given that a carburizing heat treatment of 15 hour will raise the carbon concentration by 0.35 wt% at a point of 2 mm from the surface.

We have to find the time necessary to achieve the same concentration at a 6 mm position.

we know that \frac{x_1^2}{Dt}=constant where x is distance and t is time .As the temperature is constant so D will be also constant

So \frac{x_1^2}{t}=constant

then \frac{x_1^2}{t_1}=\frac{x_2^2}{t_2} we have given x_1=2 mm\ ,t_1=15 hour\ ,x_2=6\ mm and we have to find t_2 putting all these value in equation

\frac{2^2}{15}=\frac{6^2}{t_2}

so t_2=135\ hour
