The purification of hydrogen gas is possible by diffusion through a thin palladium sheet. calculate the number of kilograms of hydrogen that pass per hour through a 2.4-mm-thick sheet of palladium having an area of 0.63 m2 at 500°c. assume a diffusion coefficient of 2.0 × 10-8 m2/s, that the concentrations at the high- and low-pressure sides of the plates are 2.7 and 0.68 kg of hydrogen per cubic meter of palladium, and that steady-state conditions have been attained.

answer: 500 wph.

explanation:

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.
