2.50 moles of an ideal triatomic gas is expanded reversibly and isothermally ( 25 degrees Celsius ) from Pi = 5.00 atm to Pf = 1.00 atm. Sketch a diagram using a piston. Estimate the values of Vi , Vf, delta U, w, q, delta A, delta S, delta H and delta G.
Consider one mole of an ideal gas at 25.0degree C. Calculate q, w, delta E, delta H, delta S, and delta G for the expansion of this gas isothermally and irreversibly from 2.45 times 10^-2 atm to 2.45 times 10^-3 atm in one step. Calculate q, w, delta E, delta H, delta S, and delta G for the same change of pressure as in part (a) but performed isothermally and reversibly. Calculate q, w, delta E, delta H, delta S,...
Sam studies a mixture of helium and argon of one liter at 25 degrees celsius and 1 atm pressure in a cylinder. He brings the cylinder in contact with liquid nitrogen (66K) at which a small amount of a white substance deposits on the walls of the cylinder and the volume of the gas reduced to 220mL. The pressure remains constant. Neglecting the volume of the solid formed, what was the partial pressure of the helium at 25 degrees celsius?...
To decide whether AgCl should dissolve in water ( spontaneous reaction ) at 25 degrees celcius, the delta H and T delta S must be used in the Gibbs Free Energy equation to calculate delta G AgCl (s) + H2O (I) -> Ag+ + Cl- + H2O Standard Enthalpies of formation and standard entropies of common compounds substance state AgCl s -127010 96.20 Cl- aq -167080. 56.50 Ag+ aq. 105790. 72.70
