please help out with these questions, especially the first one. thank you

Answer the following questions using complete sentences and support your answers with calculations, if desired. Attach additional pages as necessary. Handwritten or typed answers are acceptable. (5 pts per question) 1. Describe in your own words or figures why the addition of non-volatile solutes lower the freezing point of a solvent. (Utilize the theory of entropy in your explanation.) 2. If salicylic acid dissociated into two particles when dissolved into myristic acid (it does not), would this change your calculated Kf value? Explain why. (Hint: look over your notes on the van't Hoff factor, from lecture, for help.) 3. You estimated the freezing point of the salicylic acid-myristic acid solution, during the lab, as lower than it should have been. How would this change your calculated Ki value versus the true Kf value? Explain why the calculated K1 value would change. 4. Assume that we used a solute with a larger molar mass than salicylic acid, would this change T1 compared to the salicylic acid solution? Assume the same solvent is used and molality of the solution is unchanged. Explain why or why not
