The average kinetic energy of a mole of substance is determined from the formula, E=1.5RT where R is 8.314 J/mol K. Substituting temperature of zero kelvin to the equation, the energy is zero. It is recalled that at zero kelvin or absolute zero temperature, all molecules are not moving.
Answer:
Volume is 0.0247L
Explanation:
This question involves the use of Boyle's law which states that the volume of a given mass of gas is inversely proportional to it's pressure provided that temperature remains constant.
Mathematically,
v = k/p
K = VP
P1V1 = P2V2 = P3V3 = .........=PnVn
V = volume
p = pressure
Data;
P1 =1.0atm
V1 = 1.73L
P2 = 70atm
V2 = ?
P1V1 = P2V2
V2 = P1V1 / P2
V2 = (1.0×1.73)/70
V2 = 0.0247L
The volume of the sample is 0.0247L
Answer:
Explanation:
Hi, the first step is to calculate how much F2 there is in the container:
<u>Fluorine can be considered as an ideal gas</u> (given that is non-polar and has a small molecule). Using the ideal gas formula:
Where:
Now, the mols of iodine:
<u>The chemical reaction described is the following</u>:
In this case, the limitant reactant is the fluorine:
1) The 0.056 mol of F2 gives of and consumes of I2.
2) At the end, in the conteiner we have:
of
of
of
In total: .All in 2.5 L at 550 K
<u>The final pressure</u>:
The partial pressure:
<em>Note: this partial pressure is calculated by the Dlaton's principle</em>
The equilibrium position will shift in order to counterbalance the change. That means the equilibrium position will shift, lowering the pressure once more.... When the pressure on a gas reaction is increased, the equilibrium moves to the side with fewer molecules.
