Um dos mais importantes usos da amônia é como reagente na primeira etapa da rota sintética para produção de ácido nítrico. Essa primeira etapa, não balanceada, ocorre de acordo com a equação NH3(g) + O2(g) <--> NO(g) + H2O(g).

A expressão para a constante de equilíbrio dessa reação é:
Escolha uma:
a. Keq = ([NO]4[H2O]6) / ([NH3]4[O2]5).
b. Keq = ([NO]2[H2O]3) / ([NH3]2[O2]5).
c. Keq = ([NH3][O2]) / ([NO][H2O]).
d. Keq = ([NH3]4[O2]5) / ([NO]4[H2O]6).
e. Keq = ([NO]4) / ([NH3]4[O2]5).

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.

Compare the equilibrium constants for the systems shown in the table. which favors products the most? which favors products the least? rank these systems in order from most to least in terms of favoring products rather than reactants. d > b > a > c c > a > b > d b > c > d > a a > d > c > b
