Calculate the average speed of oxygen (O2) molecules in a gas at T = 202 K,
O2 atomic mass is 32 amu, where the atomic mass unit (amu) is 1.66 x 10-27 kg.
Provide your answer in units of meters per second, but do not include the units in your answer, just the number in normal form to 3 significant digits.
There are two particles, one is heavy and the other is light. The light particles diffuse faster than the heavy particles. This relationship is known as Graham’s Law of Effusion. Since both gases are at the same temperature, they must have the same average kinetic energy (½ mv2), where m is mass and v is the velocity (like speed). Since both gases have the same average kinetic energy, you can state that ½ mLvL2 = ½ mHvH2. Multiplying both sides by 2 gives you mLvL2 = mHvH2. Rearranging the equation to get both masses on the same side of the equation will give you mL/mH = VH2/VL2. In 3a and 3b, you probably noticed that the heavy gas particles took twice as long to diffuse as the light gas particles. This means that the light gas particles are moving twice as fast, VH/VL = ½. Therefore, VH2/VL2 = ¼. How many times heavier is the heavy gas compared to the light gas? If the light gas was Ne, what would be a reasonable identity for the heavy gas?
Q1.A glass vessel was filled with an unknown quantity of nitrogen gas and the pressure at 28°C was 4.2 x 10⁴Pa. Oxygen gas was introduced at the same temperature until the pressure was to 1.013 ×10⁵Pa.
(I) calculate the partial pressures of nitrogen gas and oxygen gas
(II) calculate the mass ratio of the two gases. ( N=14, O=16)
Q2. When temperature is increased by 10K, what happens to the rate of reaction? Why is it so?
