Graham's Law Wkst AP Chem; Coleman 1. The effusion rate of an unknown gas is measured and found to be 31.50 mL/min. Under identical experimental conditions, the effusion rate of O 2 is found to be 30.50 mL/min. If the choices are CH 4, CO, NO, CO 2, and NO 2, what is the identity of the unknown gas? 2.
density, in the light of Graham's law, suggests a potential problem in using natural gas pipelines for sending hydrogen if we should ever adopt hydrogen as an alternative fuel to methane. What is this problem? Compare the rate of effusion of hydrogen to the rate for methane. (2.83 H faster than CH 4) WORKSHEET #8 Effusion

This difference in density, in the light of Graham's law, suggests a potential problem in using natural gas pipelines for sending hydrogen if we should ever adopt hydrogen as an alternative fuel to methane. What is this problem? Compare the rate of effusion of hydrogen to the rate for methane.
The rate of effusion of a gaseous substance is inversely proportional to the square root of its molar mass. This relationship is referred to as Graham’s law, after the Scottish chemist Thomas Graham (1805–1869).
