Problem 16.3

The indicator methyl orange has been added to both of the following solutions. Based on the colors, classify each statement as true or false:

(a) The pH of solution A is definitely less than 7.00.

(b) The pH of solution B is definitely greater than 7.00.

(c) The pH of solution B is greater than that of solution A. [Section 16.4]

Step-by-Step Solution:

Step 1 of 5) Now let’s consider another example, the expansion of an ideal gas at constant temperature (referred to as an isothermal process). In the cylinder-piston arrangement of Figure 19.4, when the partition is removed, the gas expands spontaneously to fill the evacuated space. Can we determine whether this particular isothermal expansion is reversible or irreversible Because the gas expands into a vacuum with no external pressure, it does no P9V work on the surroundings. (Section 5.3) Thus, for the expansion, w = 0. We can use the piston to compress the gas back to its original state, but doing so requires that the surroundings do work on the system, meaning that w 7 0 for the compression. In other words, the path that restores the system to its original state requires a different value of w (and, by the first law, a different value of q) than the path by which the system was first changed. The fact that the same path cannot be followed to restore the system to its original state indicates that the process is irreversible.
