    Answer:

    Substance 1 will diffuse at a faster rate.

    Explanation:

    We can solve this problem by keeping in mind Fick’s law, which states:

    • J = -D * (dc/dx)

    Where:

    • J is the flux
    • D is the diffusion constant
    • (dc/dx) is the concentration gradients

    As (dc/dx) is equal for both substances, as stated by the problem, the substance with the higher diffusion constant will diffuse at a faster rate.

    Thus the answer is substance 1.
