Oxygen is diffusing through a staganant layer of methane 5 mm thick. The temperature is 0o C and the
pressure of 1 atmosphere. Calculate the rate of diffusion of oxygen in kilograms per hour through 1 m2
of methane film when the concentration change across the film is 15% to 5% oxygen by volume. The
value of diffusivity may be taken as 0.184 cm2
/s. R = 82.06 cm3
atm/ g mol K.

sorry what a asnns

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.
