Final answer:
The entropy of mixing of two liquids that form an ideal solution is given by option A) ΔS = -R(x1 ln(x1) + x2 ln(x2)). This equation calculates the change in entropy when the two liquids mix together.
Step-by-step explanation:
The entropy of mixing of two liquids that form an ideal solution is given by option A) ΔS = -R(x1 ln(x1) + x2 ln(x2)).
In this equation, x1 and x2 represent the mole fractions of the two liquids. The ln function represents the natural logarithm. R represents the ideal gas constant, which has a value of 8.314 J/(mol·K).
This equation calculates the change in entropy when the two liquids mix together. It takes into account the distribution of particles and the degree of disorder in the resulting solution.
