Question
Chapter 1, Problem 43QRT
(a)
Interpretation Introduction
Interpretation:
A black powder is placed in a long glass tube and hydrogen gas is passed into the tube so that hydrogen sweeps out all other gases. The powder is heated with Bunsen burner. It turns into red-orange and water vapour can be seen condensing at the tip of the tube. The red-orange colour remains after the tube is cooled.
The original black substance is an element or not has to be explained.

Answer the following questions about this system: Under these conditions, will the pressure of N2O4 tend to rise or fall? Is it possible to reverse this tendency by adding NO2? In other words, if you said the pressure of N2O4 will tend to rise, can that be changed to a tendency to fall by adding NO2? Similarly, if you said the pressure of N2O4 will tend to fall, can that be changed to a tendency to '2' rise by adding NO2? If you said the tendency can be reversed in the second question, calculate the minimum pressure of NO 2 needed to reverse it.

Draw only the major product or products in the drawing area below. If there's more than one major product, you can draw them in any arrangement you like. Be sure you use wedge and dash bonds if necessary, for example to distinguish between major products with different stereochemistry. If there will be no products because there will be no significant reaction, just check the box under the drawing area and leave it blank.
