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 utlize n2 for biosynthesis. bacteria capable of fixing" nitrogen (i.e., concerted n2 to a chemical form, such as nh, that can be utilized in the biosynthesis of proteins and nucleic acids) are called diazotrophs. the ability of some plants, such as legumes, to fix nitrogen is due to a symbiotic relationship between the plant and nitrogen fixing bacteria that live in the plant's roots. assume the hypothetical reaction for fixing nitrogen biologically is a. calculate the standard enthalpy change for the biosynthetic fixation of nitrogen at t-298 k. for nh,(aq), ammonia dissolved in aqueous solution, b. in some bacteria, glycine is produced from ammonia by the reaction: calculate the standard enthalpy change for this reaction. for glycine, assume t-298.15k. c. calculate the standard enthalpy change for the production of 1 mole of glycine and water from nitrogen, oxygen, and methane.
