Q. The equilibrium cell potential of the galvanic cell
is found to be Ecell,eq = 1.410 V at 298.15K. The standard cell potential is Ecell,eq = 1.360V.
(a) Write the cell reaction and calculate its thermodynamic equilibrium constant at 298.15K.
(b) Use the cell measurement to calculate the mean ionic activity coefficient of aqueous HCl at 298.15K and a molality of 0.500 mol kg-1.
How many ion H2- does have The H2- ion having three electrons. This can be conceived as the combination of a hydrogen atom with a hydride ion (H-). By the aufbau principle, two
Initially 5 mol of an ideal gas with Cv,m=12.5 J K^-1 mol^-1 are at a volume of 5 dm^3 and a temperature of 300K. If the gas is heated to 373 K and the volume changed to 10 dm^3, w
