When one mole of nitrogen gas, N2, reacts with one mole of 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 of ΔH indicate? c. Is the reaction endothermic or exothermic? what happens to heat when the reaction takes place? d. If 3 moles of nitrogen gas, N2, are made to react with three moles of oxygen gas, O2, how much heat is required in the process?

b. What does the sign of ΔH indicate?
c. Is the reaction endothermic or exothermic? what happens to heat when the reaction takes
place?
d. If 3 moles of nitrogen gas, N2, are made to react with three moles of oxygen gas, O2, how
much heat is required in the process?
e. How much heat will be released if two moles of nitric oxide, NO, are broken down into one
mole of nitrogen gas, N2, and one mole of oxygen gas, O2?
