Answer:
b. contains no positive statements.
We are given the series of chemical reactions:
Ethane is chlorinated in a continuous reactor:
C2H6 + Cl2 --> C2H5Cl + HCl
But some of the product monochloroethane becomes further
chlorinated by an undesired side reaction:
C2H5Cl + Cl2 --> C2H4Cl2 + HCl
So to avoid the product monochloroethane to be further
chlorinated, there must be fast processing or fast conversion of ethane so that
there would less time for further chlorination. Hence we must design the
reactor for high conversion of ethane.
To make the process economical, there must be a
downstream separation step that would separate the main product monochloroethane
from the undesired product dichloroethane.
Answer:
D. Qualitative methods
Explanation: Research methods are the various Strategic actions and techniques used to carry out a research, it can also be said to the techniques through which a researcher collect data or materials needed for the research.
Qualitative research methods are techniques used in research which involves open ended questions and Communications.
IN QUALITATIVE RESEARCH METHODS ARE SPECIFICALLY DESIGNED TO ENHANCE OPEN COMMUNICATION,IT HELPS THE RESEARCHER TO GET IN DEPTH KNOWLEDGE ABOUT THE RESEARCH AUDIENCE.
