Video transcript

Hi everyone here, we have a question asking us to consider the graph below, comparing the velocity distribution of the same molecule at three different temperatures, 25°C, 50°C and 75°C. And our goal here is to identify which curve represents the gas at 50°C. The speed of the molecules in gasses proportional to the temperature. As the temperature of a sample of gas is increased, the molecules speed up At 50°C. We have the middle temperature, meaning our speed should also be in the middle and when we look at our options, B has the speed that is also in the middle. It's peak is between A and C. So our answer here is B. Thank you for watching. Bye.

Imagine that the reaction 2 CO1g2 + O21g2¡2 CO21g2 occurs in a container that has a piston that moves to maintain a constant pressure when the reaction occurs at constant temperature. Which of the following statements describes how the volume of the container changes due to the reaction: (a) the volume increases by 50%, (b) the volume increases by 33%, (c) the volume remains constant, (d) the volume decreases by 33%, (e) the volume decreases by 50%.

Textbook Question

The apparatus shown here has two gas-filled containers and one empty container, all attached to a hollow horizontal tube closed at both ends.

a. How many blue gas molecules are in the left container?

b. How many red gas molecules are in the middle container?

c. When the valves are opened and the gases are allowed to mix at constant temperature, how many atoms of each type of gas end up in the originally empty container? Assume that the containers are of equal volume and ignore the volume of the connecting tube. [Section 10.4]
