J.J. Thomson hypothesized and discovered that the atom was not the smallest unit of matter but that instead there were much smaller units. He discovered "sub-atomic particles" which make up atoms. The sub-atomic particle that Thomson discovered was the electron. He discovered this through a process of experiments testing cathode rays.
Answer:
The answer is maybe reactivity
Answer:
- <u>First choice: 0.042</u>
Explanation:
Given decomposition reaction:
- 1PCl₅ (g) ⇄ 1PCl₃ + 1Cl₂(g)
Equilibrium constant:
Stoichiometric coefficients and powers equal to 1 are not usually shown as they are understood, but I included them in order to shwow you how they intervene in the equilibrium expressions: each concentration is raised to a power equal to the respective stoichiometric coefficient in the equilibrium equation.
So, your calculations are:

Answer:
The reaction rate becomes quadruple.
Explanation:
According to the law of mass action:-
The rate of the reaction is directly proportional to the active concentration of the reactant which each are raised to the experimentally determined coefficients which are known as orders. The rate is determined by the slowest step in the reaction mechanics.
Order of in the mass action law is the coefficient which is raised to the active concentration of the reactants. It is experimentally determined and can be zero, positive negative or fractional.
The order of the whole reaction is the sum of the order of each reactant which is raised to its power in the rate law.
Thus,
Given that:- The rate law is:-
![r=k[A_2][B_2]](https://tex.z-dn.net/?f=r%3Dk%5BA_2%5D%5BB_2%5D)
Now,
and ![[B'_2]=2[B_2]](https://tex.z-dn.net/?f=%5BB%27_2%5D%3D2%5BB_2%5D)
So, ![r'=k[A'_2][B'_2]=k\times 2[A_2]\times 2[B_2]=4\times k[A_2][B_2]=4r](https://tex.z-dn.net/?f=r%27%3Dk%5BA%27_2%5D%5BB%27_2%5D%3Dk%5Ctimes%202%5BA_2%5D%5Ctimes%202%5BB_2%5D%3D4%5Ctimes%20k%5BA_2%5D%5BB_2%5D%3D4r)
<u>The reaction rate becomes quadruple.</u>
