Answer:
The correct answer is option 3.
Explanation:
2A → B + C
First trial ;
[A] = x , Rate of the reaction = R
Rate law of the reaction can be written as:
![R=k[x]^a](https://tex.z-dn.net/?f=R%3Dk%5Bx%5D%5Ea)
..[1]
Second trial ;
[A] = 3x , Rate of the reaction = R' = 9R
Rate law of the reaction can be written as:
![R'=k[3x]^a](https://tex.z-dn.net/?f=R%27%3Dk%5B3x%5D%5Ea)
![9R=k[3x]^a](https://tex.z-dn.net/?f=9R%3Dk%5B3x%5D%5Ea)
..[2]
[1] ÷ [2]
![\frac{R}{9R}=\frac{k[x]^a}{k[3x]^a}](https://tex.z-dn.net/?f=%5Cfrac%7BR%7D%7B9R%7D%3D%5Cfrac%7Bk%5Bx%5D%5Ea%7D%7Bk%5B3x%5D%5Ea%7D)
a = 2
Rate of the reaction : ![R=k[A]^3](https://tex.z-dn.net/?f=R%3Dk%5BA%5D%5E3)
The order of the reaction is 2. This is because in the rate law expression the the power of the concentration of reactant A id 2.
Answer:
CO
Explanation:
Co, Cr, and Cu are elements. Elements cannot be broken down by a chemical change, but compounds can. and CO is a compound
Answer:
less dense
Explanation:
the reason that the density would be lower is because the air bubbles keep the maximum amount of atoms possible from being in that space. imagine pouring a glass of soda from a freshly opened bottle, at first it looks like there's a lot in the glass but as the bubbles dissipate, there's less and flat soda appears to have even less in the glass. i hope this analogy helped :)
Answer:
A polysaccharide found in animals.
Explanation:
Biomolecules are the important chemical compounds present in the living organisms and responsible for all the functional activities of the body. Four important biomolecules are carbohydrates, proteins, fats and lipids.
Glycogen is a carbhydrate made of the polymer of the glucose linked through the glycosidic bonds. The glycogen acts as the energy source and present in animals mainly. Glycogen is mainly stored in the liver and the skeletal muscles of the animals.
Thus, the correct answer is option (a).
Answer:
0.24 s-1
Explanation:
We first list the parameters as shown in the image attached. The variables are now properly substituted. This equation is used to calculate the rate constant and clearly show us the dependence of the rate constant on temperature. From this equation, we can clearly and easily see that the rate constant increases exponentially with increase in temperature of the reaction system.
