1. (25) Nitrogen is one of the most important elements in water, air and agricultural engineering. One of the processes that is critical we term nitrification which is mediated by microbiological organisms. Assuming conditions of 1atm and 25C, the following equation is a good model for nitrification: NH4+(aq)+OH+2O2(aq)NO3(aq)+H++2H2O(aq) (15) Determine the Gibbs Free Energy of this reaction (rxn) given that the [NH4+]=15mg/L;[O2]=2mg/L;[NO]=1mg/L and the pH=7.2. \{recall that pH can be used to determine the concentrations of [H+]and [OH]
