Answer:
The answer is "Choice A and Choice B"
Explanation:
The Zero-Order reactions are usually found if a substrate, like a surface or even a catalyst, is penetrated also by reactants. Its success rate doesn't depend mostly on the amounts of the various reaction in this reaction.
Let the Rate = k
As 
doesn't depend on reaction rate, a higher reaction rate does not intensify the reaction.
By the rate 
the created based and the reaction rate is about the same.
Answer:
The temperature at which a glass transforms from a liquid to solid.
Explanation:
Glass transition temperature is defined for polymers, so is the temperature at above which the soft and ductile polymer changes into hard britle material. It basically increases the viscosity of the material. Glass transition temperature is less than the melting point temperature. So, the polymer initially showing liquid like characteristics after transition temperature shows solid like characteristics.
So, the correct answer is
The temperature at which a glass transforms from a liquid to solid.
