Two nonpolar organic liquids, hexane (C₆H₁₄) and heptane (C₇H₁₆), are mixed. (b) Hexane and heptane are miscible with each other in all proportions. In making a solution of them, is the entropy of the system increased, decreased, or close to zero, compared to the separate pure liquids?

Hello everyone. Today, we are being given the falling problem. The organic liquids tell you in and cycle of hexane are combined to form a solution valuing. And cyclo hexane are both non polar. So they're completely miserable in the solution formation, compare the entropy of the system to the separate pure liquids. So first, let's define entropy entropy in simplest terms is going to be a measure of the degree of disorder or chaos in a system. So it's a degree of chaos or disorder in a system. And so when making the solution are tall, you're going to come together and they're gonna form a homogeneous mixture. This means that they are going to mix in a sense where they completely dissolve in one another. And so as a result of this mixing, we're going to have more molecules present in the solution, which is going to directly lead to more chaos or more disorder, which is going to increase the disorder of the system. So we can conclude that the entropy of the solution is going to be greater than the entropy Of the two separate liquids. And now we find the answer choice that best relates with that, that's gonna be answer choice. A, the entropy of the system is greater than the entropy of the separate liquids. And with that, we've answered the question overall. I hope this helped head until next time.
