### Estimating the Normal Boiling Point of AmmoniaTo estimate the normal boiling point (in K) of ammonia, we will refer to the vapor pressure curve provided below.#### Ammonia Vapor Pressure CurveThe graph illustrates the relationship between the **vapor pressure (in torr)** and **temperature (in Kelvin, K)** for ammonia. - The **x-axis** represents the temperature, scaling from **150 K to 250 K**.- The **y-axis** measures the pressure, ranging from **0 torr to 900 torr**.The curve shows an exponential increase in vapor pressure as the temperature rises. #### Key Points on the Graph:- At lower temperatures (around 150 K), the vapor pressure is near 0 torr.- As the temperature increases to around 200 K, the vapor pressure begins to rise sharply.- At approximately 240 K, the vapor pressure nears 600 torr.#### Estimating the Boiling Point:The normal boiling point of a substance is the temperature at which its vapor pressure equals standard atmospheric pressure (1 atm, equivalent to 760 torr).From the graph:- Follow the 760 torr mark on the y-axis and trace it horizontally until it intersects with the vapor pressure curve.- Drop down from this intersection point to determine the corresponding temperature on the x-axis.#### Answer Choices:- 100 K- 205 K- 237 K- The normal boiling point cannot be determined from the diagram.Based on the graph, the intersection point for 760 torr is close to 237 K. Therefore, the normal boiling point of ammonia is approximately **237 K**.#### Conclusion:After reviewing the vapor pressure curve, we can determine that the normal boiling point of ammonia is **237 K**.
