Question

The behavior of \(Cl_2\) is closest to ideal gas behavior at 
 

• A. 100 °C and 10.0 atm
• B. 0 °C and 0.50 atm
• C. 200 °C and 0.50 atm
• D. -100 °C and 10.0 atm

Hint:

Ideal gas behavior is most closely approximated at low pressures and high temperatures.

Answer 1

The Correct Option is C

Step 1: Understanding ideal gas behavior. 
For gases to behave ideally, the temperature should be high, and the pressure should be low. The given temperature and pressure in option (C) are likely to lead to ideal gas behavior. 
 

Step 2: Analyzing the options. 
(A) 100 °C and 10.0 atm: Incorrect — At higher pressures, gases deviate from ideal behavior. 
(B) 0 °C and 0.50 atm: Incorrect — Although the pressure is low, the temperature is very low.
(C) 200 °C and 0.50 atm: Correct — This combination is closest to the conditions for ideal gas behavior. 
(D) -100 °C and 10.0 atm: Incorrect — Both the low temperature and high pressure result in deviations from ideal gas behavior. 
 

Step 3: Conclusion. 
The correct answer is (C) because this temperature and pressure are closest to ideal gas behavior.
