The rate law for a hypothetical reaction is rate = k [A]2. When the concentration is 0.10 moles/liter, the rate is 2.7 × 10-5 M*s-1. What is the value of k?
Answers
Answer:The value of rate constant is .
Explanation:
Concentration of [A]=0.10 mol/L
The rate of the reaction =
Rate constant = k
The given rate law:
The value of rate constant is .
Given:
rate = k [A]2
concentration is 0.10 moles/liter
rate is 2.7 × 10-5 M*s-1
Required:
Value of k
Solution:
rate = k [A]2
2.7 × 10-5 M*s-1 = k (0.10 moles/liter)^2
k = 2.7 x 10^-3 liter per mole per second

The answer is:
Sublimation
The explanation:
The most state has the high volume is the gas state.
So here the answer is between vaporization and sublimation???
and when the sublimation is: the change of the material from the solid state to the gas state directly without pass to liquid state from the solid first then to the gas
and the vaporization is : The change of the material from the liquid state to the gas state by heating Ex: water vaporize at 100°
here, the answer is sublimation because the difference of volume which resulted from this process is more than the volume resulted from vaporization.
Answer: The correct answer is Option 4.
Explanation:
All these processes are the physical processes which occurs between the phases of matter.
Solid state is the phase where particles are closely arranged and the volume of this state is less.
Liquid state is the phase where particles are not closely arranged and the volume of this state is more than solid but less than gaseous state.
Gaseous state is the phase where particles are loosely arranged and this state has the largest volume.
- Deposition is the physical process in which gaseous state is converted to solid state. The volume of the substance decreases.
- Melting is the the physical process in which solid state is converted to liquid state. The volume of the substance increases.
- Vaporization is the physical process in which liquid state is converted to gaseous state. The volume of the substance increases.
- Sublimation is a physical process in which solid states is converted to gaseous state. The volume of the substance increases and in this case, the increment in volume is the maximum.
Hence, the correct answer is Option 4.
