Read the descriptions of physical or chemical changes in the table below. Then decide whether the change will be spontaneous, if you can. Change A gas condenses to a liquid, neither absorbing nor releasing heat. An exothermic chemical reaction between a solid and a liquid results in gaseous products. Two liquids mix, neither absorbing nor releasing heat. Is this change spontaneous? Yes. No. Can't decide with information given. ○ Yes. ○ No. Can't decide with information given. Yes. No. ○ Can't decide with information given.
Calculate ΔS when 25.0 g ethanol at 50.0 °C is added to 75.0 g ethanol at 10.0 °C in an insulated container where Cp = 111.5 J/mol K. Calculate the change in entropy of each ethanol sample, and then the total entropy change. Comment on what is happening to each sample, and overall. (answers: warm = -6.11 J/K; cold = +5.69 J/K; total = 0.42 J/K)

Which one of the systems would have more entropy and why if there's 3 particles w a total energy of 12 J
For a particular reaction at 148.1 °C, delta G=−1428.51 kJ, and delta S =393.69 J/K . Calculate delta G for this reaction at −62.8 °C. Free energy is related to enthalpy, temperature, and entropy through the equation delta G = delta H -T(delta S) Δ?=Δ?−?Δ? delta H = delta G + T (delta S) Solve for the enthalpy of the reaction. Assume that enthalpy and entropy will not change between the two temperatures. Use the values from the prior scenario (temperature) to determine the new free energy value using the first equation.
