Answer to Question #258575 in General Chemistry for Loyd

Question

When one mole of nitrogen gas,N2, reacts with one mole oxygen gas,O2, two moles of nitric oxide,No,are formed.In the process,180.5 kJ of heat are required. A.write the thermochemical equation for the chemical reaction( use two ways in writing the equation). B.what does the sign ∆H indicates. C.Is the reaction endothermic or exothermic? What happens to heat when the reaction takes place?

Answer 1

$N2 + O2 -->2NO$

∆H is the enthalpy change

The reaction is endothermic
