**Explanation:**
The generalized compressibility chart is a plot that helps in analyzing the behavior of real gases by using the concept of reduced variables. The reduced variables are obtained by dividing the actual values of pressure, temperature, and volume by their respective critical values.
The chart is constructed by plotting the reduced temperature (Tr) on the x-axis and the reduced pressure (Pr) on the y-axis. The compressibility factor (Z) is represented by different contours or lines on the chart.
**Purpose of the Generalized Compressibility Chart:**
The generalized compressibility chart is used to determine the compressibility factor (Z) for a given gas at different combinations of pressure and temperature. The compressibility factor provides information about the deviation of a real gas from the ideal gas behavior. It is defined as the ratio of the actual volume of a gas to the volume predicted by the ideal gas law.
**Understanding the Chart:**
The chart is divided into different regions based on the behavior of gases at different combinations of pressure and temperature. The regions include the ideal gas region, the subcritical region, and the supercritical region.
The ideal gas region is represented by a straight line passing through the origin, where Z is equal to 1. In this region, the gas behaves ideally, following the ideal gas law.
The subcritical region is located below the critical isotherm (Tr = 1) and is characterized by compressibility factors less than 1. In this region, the gas exhibits attractive forces and deviates from ideal gas behavior, leading to lower compressibility factors.
The supercritical region is located above the critical isotherm and is characterized by compressibility factors greater than 1. In this region, the gas exhibits repulsive forces and deviates from ideal gas behavior, leading to higher compressibility factors.
**Significance of Reduced Variables:**
The use of reduced variables allows for the comparison of the behavior of different gases on the same chart. By normalizing the pressure, temperature, and volume with their respective critical values, the effect of the gas type is eliminated, and only the thermodynamic behavior is considered.
Therefore, the generalized compressibility chart is plotted with reduced temperature on the x-axis, reduced pressure on the y-axis, and Z represented by different contours or lines. This representation allows for easy analysis and comparison of gas behavior at different pressure and temperature conditions.
Hence, the correct answer is option 'b' - when reduced temperature is plotted as a function of reduced pressure and Z.
