Compute the cell potential(E) after the reaction has operated long enough for the [Al3+] to have changed by .60 mol/L. suppose T=25 C
an ideal gas with temperature independent Cp = (7/2)R at 15 degrees C and having initial volume 60 m^3 is heated at constant pressure (P =0.1013 MPa) to 30 degrees by transfer of heat from a resivoir at 50 degrees C.
A vessel containing 45.0 cm3 of helium gas at 25°C and 106 kPa was inverted and placed in cold ethanol. As the gas contracted, ethanol was forced into the vessel to maintain the same pressure of helium.
