Rates of diffusion are often given in moles per second. Rates of diffusion usually vary with distance and we can examine the diffusion across a square meter. Assuming we study the diffusion of carbon dioxide across this square meter at different temperatures but otherwise identical conditions, what is the predicted rate of diffusion of carbon dioxide at 78°C if the rate of diffusion at 32°C across this square meter is 5.2 × 10^{–9} moles/sec?

Step 1

It is given that:

Temperature (T_{1}) = 32 ˚C

Temperature (T_{2}) = 78 ˚C

Rate of diffusion D_{1} = 5.2×10^{-9} moles/s

Step 2

Rate of Diffusion is directly proportional to the square root of temperature. The expression for this is represented as follows:

Step 3

As the initial temperature T1 and T2 is given in degree Celsius...
