is not spontaneous. However, the process
is spontaneous at 1500 K. Explain.
Answer to relevant QuestionsUsing the following data, calculate the value of Ksp for Ba(NO3)2, one of the least soluble of the common nitrate salts. The standard entropy values (So) for H2O(l) and H2O(g) are 70. JK-1mol-1 and 189 JK-1mol-1, respectively. Calculate the ratio of Vg to Vl for water using Boltzmann’s equation. (See Exercise 22.) Consider 1.0 mole of a monatomic ideal gas in a container fitted with a piston. The initial conditions are 5.0 L and P = 5.0 atm at some constant T. a. If the external pressure is suddenly changed to 2.0 atm, show that ...Liquid water at 25oC is introduced into an evacuated, insulated vessel. Identify the signs of the following thermodynamic functions for the process that occurs: ΔH, ΔS, ΔG, ΔTwater, ΔSsurr, ΔSuniv. The initial state of an ideal gas is 2.00 atm, 2.00 L. The final state is 1.00 atm, 4.00 L. The expansion is accomplished isothermally. a. If the expansion is a free expansion, calculate w, q, ΔE, and ΔH. b. If the ...
