A very low value of equilibrium constant for a reaction can indicate that?
Favors the reactants.
Why resorcinol is used as a reagent in test in seliwanoff test?
Resorcinol is used as the complexing agent to provide the color reaction, although the exact nature of the colored product is not known. Since resorcinol favors electrophilic aromatic substitution, the reaction may be similar to the Molisch Test.
What condition that favors negative nitrogen balance?
Pregnancy
Which of the following favors formation of an ionic compound?
c)
What are the advantages and disadvantages of exothermic and endothermic reactions?
The big advantage to being exothermic is that the animals save a huge amount of energy. In contrast, endothermal or warm blooded animals use roughly one third of the energy they ingest for heating. The big disadvantage in being exothermic is that moving, digesting and reproducing generaly use more energy and take longer to start up.
On what conditions does a spontaneous reaction become spontaneous?
For some non-spontaneous reactions, you can change the temperature. For other non-spontaneous reactions, there is nothing you can do to make it spontaneous. Nature favors reactions that increase a system's entropy (disorder) and nature favors reactions that are exothermic (they release enthalpy). Any reaction that does both of these things is spontaneous at all temperatures. Any reaction that does neither of these things is never spontaneous. As far as this question is concerned, the interesting reactions are endothermic reactions that increase entropy and exothermic reactions that decrease entropy. Whether these reactions are spontaneous depends on the temperature. The first variety (endothermic, increase entropy) will be spontaneous at high temperatures; the second (exothermic, decrease entropy) will be spontaneous at low temperatures. To find the temperature at which a reaction becomes spontaneous, one may apply the Gibbs equation: DG = DH - TDS where capital Ds stand for the Greek capital delta.
Is it true when a reaction is at a equilibruim increasing the temperature favors the reaction that releases energy as heat?
No that is false. Increasing temperature favors the reaction that absorbs energy, not that releases energy as heat.
In low temperature which factors favor a forward reaction?
At a low temperature, which of these factors favors a forward reaction
Why a catalyst is not involved chemically in chemical reaction?
The catalyst is not a reactant; a catalyst only favors a chemical reaction, the reaction rate and yield.
A very low value of equilibrium constant for a reaction can indicate that?
Favors the reactants.
Le Chatelier's principle states that increasing temperature favors a reaction?
That requires energy as heat
What determines a compounds reactivity in an SN2 reaction?
Stearic hindrance and stability of carbonium ion, less stearic hindrance and less stability of carbonium ion favors the SN2 reaction.
What are favors you can get from your girlfriend?
It depends: what "favors" can she get from you?
Compare the relative ease of oxidation of primary secondary and tertiary butyl alcohol toward acid dichromate based on the time required for the solution to change color?
primary alcohols react the fastest, with secondary alcohols next and tertiary alcoholsnot reacting at all. This is because the mechanism of this reaction is Sn1 which is a substituion reaction that favors attack on less crowded molecules
What is the birth name of Greg Favors?
Greg Favors's birth name is Gregory Bernard Favors.
How tall is Alexander Favors?
Alexander Favors is 6'.
