Hydrogen has been suggested as the fuel of the future. One way to store it is to convert it to a compound that can be heated to release the hydrogen. One such compound is calcium hydride, Cal-12. This compound has a heat of formation of -186.2 kJ/mol and a standard entropy of 42.0 J/mol K. What is the minimum temperature to which calcium hydride would have to be heated to produce hydrogen at one atmosphere pressure?
