(a)
Interpretation:
The decreasing standard molar entropy
Concept introduction:
Entropy is a thermodynamic quantity, which is the measure of randomness in a system. The term entropy is useful in explaining the spontaneity of a process. For all spontaneous process in an isolated system there will be an increase in entropy. Entropy is represented by the letter ‘S’. It is a state function. The change in entropy gives information about the magnitude and direction of a process. The entropy of one mole of substance at a given standard state is called standard molar entropy (

In thermodynamics entropy is the term that measures the randomness of the system. The system can have different energy levels and the constituent particles such as atoms and molecules can be arranged in different possible ways. The different possible arrangements of particles are called as the thermodynamic probability. The different possible arrangements are also called as microstates.

- Question 19 0/2 pts 3 Details You have a mixture of sodium chloride (NaCl) and potassium chloride (KCl) dissolved in water and want to separate out the Cl- ions by precipitating them out using silver ions (Ag+). The chemical equation for the net ionic reaction of NaCl and KCl with silver nitrate, AgNO3, is shown below. Ag+(aq) + Cl(aq) → AgCl(s) The total mass of the NaCl/KCl mixture is 1.299 g. Adding 50.42 mL of 0.381 M solution precipitates out all of the Cl-. What are the masses of NaCl and KCl in the mixture? Atomic masses: g: Mass of NaCl g: Mass of KCL Ag = 107.868 g mol- 1 Cl = 35.453 g mol- 1 K = 39.098 g mol- N = 14.007 g mol−1 Na = 22.99 g mol−1 0 = 15.999 g mol 1 Question Help: ✓ Message instructor Submit Questionarrow_forwardPart 1. Draw monomer units of the following products and draw their reaction mechanism (with arrow pushing) Polyester fiber Using a) pthalic anhydride + anhydrous sodium acetate + ethylene glycol B)pthalic anhydride + anhydrous sodium acetate + glycerolarrow_forwardIdentify the missing starting materials/ reagents/ products in the following reactions. Show the stereochemistry clearly in the structures, if any. If there is a major product, draw the structures of the major product with stereochemistry clearly indicated where applicable. Show only the diastereomers (you do not have to draw the pairs of enantiomers). If you believe that multiple products are formed in approximately equal amounts (hence neither is the major product), draw the structures of the products, and show the detailed mechanism of these reactions to justify the formation of the multiple products. If you believe no product is formed, explain why briefly. (6 mark for each, except f and g, which are 10 mark each)arrow_forward
