Using the the data in the provided Thermodynamic Data Table, calculate the standard free energy change in kJ for the following reaction at 25 °C. H 2O(l) → H 2O(g)   Enter the numerical answer in decimal format, do not include units

Given the following data, calculate ΔGorxn to determine if the reaction Ti(s) + 2Cl2(g) -> TiCl4(l) is spontaneous under standard conditions given ΔHof(TiCl4(s))=−804.2 kJ/mol and ΔHof(Cl2)=ΔHof(Ti(s))=0 kJ/mol.

Use the reaction for the formation of NH3 from its elements N2(g) and H2(g) . This reaction has the following thermodynamic data:  ΔfHo (NH3) = - 45.9 kJ/mol and ΔfSo (NH3) = - 99.1 J/mol*K at 298 K a) Write a balanced equation (whole number ratios) for this process and write out the expression for the reaction quotient Q using partial pressures. b) Without doing any calculations, explain how the progression of the reaction will change (more reactants or more products) with respect to 1) increasing temperature, and 2) increasing pressure. c) Calculate the equilibrium constant K at 298 K d) Assuming that : ΔfHo  is independent of temperature, calculate K at - 78o C

A helium-filled balloon at 1.00 atm pressure has a volume of 1.200 L. It is placed in a freezer and its volume decreases, stopping at 1.010 L.  (Assume that the static internal and external pressures are equal, that the balloon contains only helium, and helium behaves as an ideal gas.)  Calculate ΔE for the gas in the balloon.
