The efficient design of chemical plants depends on the designer’s ability to access and use the heat output in one process to supply another process. The standard enthalpy of reaction for N2(g) + 3H2(g) -> 2NH3(g) is -92.22 kJ/mol. What is the change in enthalpy when (a) 568 kg of N2 (g) is consumed? _______ kJ. 3 sig. number in exponential format, e.g. 3.45E5, 5.32E-6, -4.44e3,.... (b) the change in enthalpy when 1,308.5 kg of NH3 (g) is formed. _____ kJ. 3 sig. number in exp. format.
