Question

The critical temperature of O2 and N2 are 155K and 126K respectively. calculate the ratio of reduced temperatures of O2 and Nè at 300K​

Answer 1

Given info: The critical temperature of O2 and N2 are 155K and 126K respectively.

To find: Calculate the ratio of reduced temperatures of O₂ and N₂ at 300K.

Solution: We​ know that,

• Expression for Reduced temperature of a gas is
•           Tr = T/Tc, where Tc is the critical temperature of a gas at 'T'             temperature.

Now, Reduced temperature for O₂ = 300K/155 K

• Reduced temperature for N₂ = 300K/126 K
• Required ratio =(300K/155 K)/(300 K/126K)
•                         = 126/155

•                         = 0.813

Hence, the ratio of reduced temperatures of O₂ and N₂ is 0.813.
