there is no relationship between efficiency and resolution
increase by a factor of two
increase by a factor of the square root of two
decrease by a factor of two
decrease by a factor of the square root of two
If the efficiency of a chromatographic column is doubled, by how much will the resolution change?...
In an isothermal gas chromatographic method with a capillary column. If you increase the temperature in the oven. What effect does this have on retention time, retention factor, plate height, plate number, resolution and separation factor?
Chromatography column resolution Example: A column has an efficiency of 14,000 theoretical plates. It has a to value of 1.3 min. Two analytes have retention times of 10.4 and 12.2. Calculate their resolution factor
If the __________ doubled, how would blood flow change and by how much? a. radius b. blood viscosity c. vessel length d. pressure
Part A Given the following rate law, how does the rate of reaction change if the concentration of X is doubled? Rate = k[X] [Y] The rate of reaction will increase by a factor of 2. The rate of reaction will increase by a factor of 6. The rate of reaction will increase by a factor of 8. The rate of reaction will decrease by a factor of 2. The rate of reaction will remain unchanged. Submit Request Answer
To obtain a resolution of 1.50, how many theoretical plates must a packed column have for two peaks which elute at 5.42 and 5.63 minutes, where tm = 1.00 min? With a resolution of 1.50, are these peaks considered to be resolved?
16. What is the relationship between free energy change of a reaction and the equilibrium constant? A B C D 17. The rate law for the reaction is first order in [A] and second order in [B]. If [A] is halved and [B] is doubled, by what factor does the rate increase, decrease, or remain the same? Explain 18. Consider the potential energy diagram shown below to answer the following question? Where is the transition state of the slower step....
The electrostatic force between two charges is 1.8 × 10–6 N when q1 = q2; that is, when the charges are equal in magnitude. If the magnitude of q1 only is now doubled, what happens to the force between them if the distance between them is not changed? The force would increase by a factor of 2. The force would increase by a factor of 4. There would be no change in the force as the distance between the charges...
A typical Si-based PV cell will have a form factor, FF=0.7, and an open circuit voltage VOC=0.6 V and a short-circuit current density JSC=30 mA/cm2. What is the maximum real efficiency of this cell? Suppose now that by improving the manufacturing process, you are able to increase the carrier lifetime by a factor of 3. If nothing else is changed in the PV cell design? By how much will the efficiency improve? Hint: JSC is proportional to square root of...
So n g price is 14th are creed How much will come change by 5.700 ? 52.700 decrease 102,000 increase 12.00 increase
Please answer the questions thoroughly. Clearly show equations used and how you will arrange them to find the relationship of the variables mentioned. Also, please don't just say if something will increase or decrease but provide a ratio (ie. if X decreased by 2, Y will decrease by 4). 1A. How would the horizontal range change if the muzzle velocity was doubled? Explain how you know. 1B. How would the horizontal range change if the height from the ground was...
