Considere a reação abaixo:
N2O5(g) 2NO2(g) + 1/2O2(g)
1. Inicialmente a concentração de N2O5 que esta dissolvido em tetracloreto
de carbono é 4,2 mol/L.
a) Qual a concentração inicial de NO2 e 02?
b) Após 1 h, ainda há N2O5 no recipiente e sua concentração é igual a
3,24mol/L. Calcule a velocidade média de decomposição da substância
no intervalo de 0 a 1 h.
c) Qual a concentração de N2O5, NO2 e O2 após 1 hora.
d) Após 2 h, a concentração de N2Os é 2,40 mol/L. Calcule a velocidade
média de decomposição dessa substância no intervalo de 1 a 2 h.
e) Qual a concentração de N2Os, NO2 e O2 após 2 horas.
f) Após 3 h, a concentração de N2Os é de 1,77. Calcule a velocidade média
de decomposição da substância no intervalo de 2 a 3 h.
g) Qual a concentração de N2Os, NO2 e Oz após 3 horas.
