Question:
An engine generates 15.7 g of nitric oxide gas during a laboratory test. How much heat was absorbed in producing this NO?
Strategy The thermochemical equation for this reaction was given earlier. This equation provides a link to convert the amount of NO formed to the energy absorbed.
As in any other stoichiometry problem, we will work with moles of substance, which we can obtain from the given mass. Note that the stated ΔHº value is for the production of 2 moles of NO because 2 moles appear in the equation.
