Critical temperatures of for NO, CO2 and CCl4 are 177 K, 304 and 550 K, respectively. Which gas is more close to ideal behaviour at 300 K?
Options:
Answer:
A
Solution:
A gas approaches ideal behaviour the farther its temperature is above its critical temperature. At 300 K: NO has T/TC = 300/177 ≈ 1.7, while CO2 (304 K) and CCl4 (550 K) are at or below their critical temperatures. NO is farthest above its TC, hence closest to ideal. Ans: (a)
