(a)
Interpretation:
Whether the entropy change for the process of boiling of water is positive or negative has to be predicted.
Concept Introduction:
Entropy change for a reaction is used to predict the randomness. A negative entropy change suggests that the overall entropy of the products is less than that of reactants which is not feasible. A reaction should have a positive entropy change. Entropy is always positive for a spontaneous process.
(b)
Interpretation:
Whether the entropy change for the dissolution of tea spoon of sugar in coffee is positive or negative has to be predicted.
Concept Introduction:
Refer to part (a).
(c)
Interpretation:
Whether the entropy change for the precipitation of calcium carbonate in caves is positive or negative has to be predicted.
Concept Introduction:
Refer to part (a).

- In the decomposition reaction in solution B → C, only species C absorbs UV radiation, but neither B nor the solvent absorbs. If we call At the absorbance measured at any time, A0 the absorbance at the beginning of the reaction, and A∞ the absorbance at the end of the reaction, which of the expressions is valid? We assume that Beer's law is fulfilled.arrow_forward> You are trying to decide if there is a single reagent you can add that will make the following synthesis possible without any other major side products: 1. ☑ CI 2.
