Answer :
The second law of thermodynamics explain the diffusion of substances is that trend of randomization. Diffusion of particles of solute from higher concentration to lower concentration lead to increase in entropy.
The second law of thermodynamics explain the trend of randomization or an increasing in entropy. if the concentration of substances on both sides are same then the distribution is random is more than the concentration is unequal. Diffusion of as substance from higher to lower leads to increase in entropy ,. when the concentration decreases entropy increases.
Thus, The second law of thermodynamics explain the diffusion of substances is that trend of randomization. Diffusion of particles of solute from higher concentration to lower concentration lead to increase in entropy.
