Answer:
<u>time taken will be halved</u>
Explanation:
we have
..................(1)
where
t = time elapsed since diffusion began
= mean distance traveled by the diffusion solute
D = Diffusion coefficient
now, according to the conditions given in the question
when, diffusion coefficient (D) doubles i.e D' = 2D
Average diffusion distance remains same i.e
substituting the values in the equation we get
or
or
...............(2)
hence, on comparing equation (1) and (2) we can say that the<u> time taken will be halved</u> when the diffusion coefficient doubles and the mean distance traveled remains the same
