Each of three identical 15.0-L gas cylinders contains 7.50 mol of gas at 295 K.Cylinder A contains HCN,cylinder B contains CO₂,and cylinder C contains O₃.According to the kinetic molecular theory,which gas has the highest pressure? A)HCN B)CO₂ C)O₃ D)All have identical pressures

Question

Quizplus · Accepted Answer

According to the kinetic molecular theory, all gases have identical pressures when they are in the same container and have the same volume, temperature, and number of molecules. The number of molecules and the temperature are identical for all three gases in this scenario, and they are all in identical containers with the same volume. Therefore, they must all have the same pressure.
