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.
2HCl + Ca = CaCl₂ + H₂
n(HCl)=cv
n(Ca)=m(Ca)/M(Ca)
n(HCl)=2n(Ca)
cv=2m(Ca)/M(Ca)
v=2m(Ca)/{cM(Ca)}
v=2*60/{1.25*40}=2.4 L
The correct answer is D . Milk
Is B. The number of the atomic mass can increase or decrease because the number of neutrons is different.
