The process is a reaction between nitrogen and water, whereby ammonia and oxygen are formed. Calculate the standard free energy and the equilibirum constant for this process, when it can be found that the standard free energy of formation of 1 mole of water (gas) is 228.6 kJ, and of 1 mole of ammonia (gas), 16.6 kJ. The standard free energy of element is, according to definition, 0.
In the density determination of aluminum a student mistakenly recorded the volume of each piece of aluminum as 2 mL greater than its actual value ( 6 mL instead of 4 mL, 8 mL instead of 6 mL).
The specific heat of water is 4.184 J/gxC. Assume the density of th water is 1.00g/mL and there is no heat lost or gained by the calorimeter.
