Assignment Help Chemistry
Reference no: EM132591108

For the combustion of 0.05371 mol of C5H12O(l) at constant pressure and a temperature of 25.00oC, we measure that 177.0 kJ of heat is released by the reaction. With this data, what would be the values of ΔH, ΔU, Q, and W for the combustion of 1.000 moles of C5H12O(l) at constant volume and a temperature of 25.00oC? Combustion is the reaction of a substance with O2(g) to produce CO2(g) and H2O(l).

We have an unknown liquid. For its evaporation, what are the signs (positive or negative) for its enthalpy change, its entropy change, and the change in the entropy of the surroundings/environment? You need not explain your answers.
