AT 15°

The rate of diffusion of a gas is directly proportional to the absolute temperature. At lower temperature the gas particles have less kinetic energy than at higher temperature. This makes the particles travel faster at higher temperature than lower temperature.

Answer from: zanaplen27

At 15° the gas will have lowest rate of diffusion.

Explanation:

Temperature directly affects the kinetic energy of gas molecules. The energy of motion is called kinetic energy. So if we increase the temperature of gas the average kinetic energy of the gas molecules will increase (they will move faster). Due to increase in kinetic energy they will easily diffuse from their higher concentration to lower concentration (which is diffusion).

Hence the rate of diffusion at given temperature will have following increasing order.

15° < 21° < 24° < 30°

1.consider the following balanced equation and answer parts a through. show calculations for each part.

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.
