Read the descriptions of physical or chemical changes in the table below. Then decide whether the change will be spontaneous, if you can. Change During an endothermic chemical reaction, four moles of gaseous reactants are turned into two moles of gaseous products. A solid precipitates from a solution, releasing heat as it does so. A solid absorbs heat and turns to a gas. Is this change spontaneous? Yes. O No. O Can't decide with information given. O Yes. O No. O Can't decide with information given. O Yes. O No. O Can't decide with information given.
You add some of the white crystals to a small test tube filled with water. The water in the test tube was initially at room temperature (25˚C). Once the crystals were added and the tube was stirred, the temperature of the solution decreased to about 15˚C and all of the crystals dissolved. what is the change in Gibbs free energy (∆G) for this process?
9. Consider the reaction NH4NO; (s) → NH4+ (aq) + NO3- (aq). When 1.25 g of NH,NO3 dissolves in enough water to make 25.0 mL of solution, the temperature of the solution drops from 25.8 °C to 21.9 °C. Determine the reaction enthalpy. (You may use 1.0 g/mL for the density and 4.18 J/g.°C for the specific heat of the solution.)
