Answer:
The correct answer is option C.
Explanation:
The given rate law of reaction :
Rate of the reaction after doubling the concentration of Y : R'
The rate of the reaction will increase by the factor of 4.
Answer:
B.
Explanation:
The force of gas molecules hitting their container is pressure.
Because pressure = force/area.
Answer:
A. absorbs light
Explanation:
For an electron to move from a lower energy level to a higher energy level, energy needs to be added to the atom.
In most cases this required energy will be light: The electron of the atom will absorb the energy of the light and move to a higher energy level.
When said electron comes back to the lower energy level, the atom will conversely give off light.
The balanced equation for the reaction is as follows
2RbNO₃ --> 2RbNO₂ + O₂
stoichiometry of RbNO₃ to O₂ is 2:1
number of moles of RbNO₃ decomposed - 5.0 mol
when 2 mol of RbNO₃ decomposes, 1 mol of O₂ is formed
therefore when 5.0 mol of RbNO₃ decomposes - 5.0 / 2 = 2.5 mol of O₂
2.5 mol of O₂ is formed
The Kelvin Scale is used, so the answer is temperature :)
