Nitrogen dioxide gas is confined at 127ºC and 2.5 atmospheres. What would be the pressure of this sample at 27ºC and the same volume?

A. 2.5 atmospheres
B. 2.0 atmospheres
C. 1.875 atmospheres
D. 1.5 atmospheres

Answer :

Final answer:

Using Gay-Lussac's law, the pressure of the nitrogen dioxide gas at 27°C and the same volume is calculated to be 1.875 atmospheres. Therefore, the correct answer is option c) 1.875 atmospheres.

Explanation:

To find out what the pressure of the nitrogen dioxide gas would be at 27°C, we can use the Gay-Lussac's law of gases, which states that for a given mass and constant volume of an ideal gas, the pressure is directly proportional to its temperature in Kelvin. We can set up a ratio using the initial and final states of the gas:

P1/T1 = P2/T2

Where:

  • P1 is the initial pressure (2.5 atm)
  • T1 is the initial temperature (127°C = 400 K)
  • P2 is the final pressure
  • T2 is the final temperature (27°C = 300 K)

We solve for P2:

P2 = P1 * (T2/T1)

P2 = 2.5 atm * (300 K / 400 K)

P2 = 1.875 atmospheres

Therefore, the pressure of the sample at 27°C and the same volume is 1.875 atmospheres.
