The efficient design of chemical plants depends on the designer's ability to assess and use the heat output in one process to supply another process. The standard enthalpy of reaction of N2 (g) + 3 H2 (g) ? 2 NH3 (g) is –92.22 kJ mole-1. What is the change in enthalpy when: (a) 1.00 mol N2 is consumed, (b) 1.00 mol NH3 (g) is formed?

Ammonia is produced directly from nitrogen and hydrogen by using the Haber process. The chemical reaction is N2(g)+3H2(g) ---> 2NH3 (g) (a) Use bond enthalpies to estimate the enthalpy change for the reaction, and tell whether this reaction is exothermic or endothermic (b) Compare the enthalpy change you calculate in (a) to the true enthalpy change as obtained using ∆Hf° values. (∆Hf° of ammonia is -46.19 kJ/mol)

1. Nitrogen is a vital component of proteins and nucleic acids, and thus is necessary for life. The atmosphere is composed of roughly 80% N2, but most organisms cannot directly utilize N2 for biosynthesis. Bacteria capable of “fixing” nitrogen ( ie converting N2 to a chemical form, such as NH3, which can be utilized in the biosynthesis of proteins and nucleic acids) are called diazatrophs. The ability of some plants like legumes to fix nitrogen is due to a symbiotic...

A calorimeter is an insulated device in which a chemical reaction is contained. By measuring the temperature change, ΔT, we can calculate the heat released or absorbed during the reaction using the following equation: q=specific heat×mass×ΔT Or, if the calorimeter has a predetermined heat capacity, C, the equation becomes q=C×ΔT At constant pressure, the enthalpy change for the reaction, ΔH, is equal to the heat, qp; that is, ΔH=qp but it is usually expressed per mole of reactant and with...
