Refer to Q9 and answer what is the enthalpy change for the reaction of 100.0 g of nitrogen with excess oxygen?(a) 1164 kJ(b) 1190 kJ(c) 1194 kJ(d) 1160 kJI have been asked this question in exam.Asked question is from Enthalpy Change Due to Reaction in division Energy Balance of Bioprocess Engineering

Answer»

Correct option is (a) 1164 KJ

The BEST I can explain: Here, we need to convert grams of N2 to moles of N2 and use the CONVERSION factor 180.6 kJ/1 mol N2.

180.6 kJ × (1 mol N2/28.01 g N2) × (180.6 kJ/1 mol N2) = 1164 kJ.
