The data for bulk chain polymerization having potassium persulfate as initiator is given- = 5 mol/m3 = 5.3*103 mol/m3 kp2/kt = 0.85*10-6 m3/ mol-s What is the initial rate of polymerization, if potassium persulfate decomposes at a rate of 2.2*10-6 m3 s/ mol?

The data for bulk chain polymerization having potassium persulfate as initiator is given- = 5 mol/m3 = 5.3*103 mol/m3 kp2/kt = 0.85*10-6 m3/ mol-s What is the initial rate of polymerization, if potassium persulfate decomposes at a rate of 2.2*10-6 m3 s/ mol? Correct Answer I

The initial rate of polymerization is here, expressed as, Rp=0.50.5. Assuming f=1, and substituting all the values, we get Rp as 0.0162 m3/ mol-s.

Seven people A, B, C, D, E, F and G live on separate floors of a 7-floor building. Ground floor is numbered 1, first floor is numbered. 2 and so on until the topmost floor is numbered 7. Each one of these having a different cars-Cadillac, Ambassador, Fiat, Maruti, Mercedes, Bedford and Fargo but not necessarily in the same order. Only three people live above the floor on which A lives. Only one person lives between A and the one having a car Cadillac. F lives immediately below the one having a car Bedford. The one having a car Bedford lives on an even-numbered floor. Only three people live between the ones having a car Cadillac and Maruti. E lives immediately above C. E is not having a car Maruti. Only two people live between B and the one having a car Fargo. The one having a car Fargo lives below the floor on which B lives. The one having a car Fiat does not live immediately above D or immediately below B. D does not live immediately above or immediately below A. G does not have a car Ambassador. Question : How many people live between the floors on which D and the one having a car Bedford ?

Which of the following statements are true?
Statement I Big data refers to no precise quantity, but generally refers to data in the range of Petabytes and Exabyte, i.e. billions to trillions of records, all from various sources. Big data is generated much faster. than traditional data in much larger quantities.
Statement II Big data interests industries because they are able to learn more patterns and curious variances than smaller data sets, with the capability to provide valuable insights into consumer behaviour, weather systems, financial market activity, or other phenomena.
Statement III Various departments and product lines use various applications within most organisations and store data in separate datasets. These separate databases may contain similar data, but data from one data base to another is not always consistent. This is called data silo.
