Question

escreva as expressões matemáticas de constante Kc:

Answer 1

a) N2 O4 --------- 2NO2

Kc = [NO2]^2 / [N2O4]

b) 2CO + O2 --------- 2CO2

Kc = [ CO2]^2 / [CO]^2.[O2]

c) H2 + I2 --------- 2HI

Kc = [HI]^2 / [H2].[I2]

d) 2N2 H4 + 2NO2 --------- 3N2 + 4H2O

Kc = [N2]^3.[H2O]^4 / [N2H4]^2.[NO2]^2

Answer 2

Resposta:

a) N2 O4 --------- 2NO2

Kc = [NO2]^2 / [N2O4]

b) 2CO + O2 --------- 2CO2

Kc = [ CO2]^2 / [CO]^2.[O2]

c) H2 + I2 --------- 2HI

Kc = [HI]^2 / [H2].[I2]

d) 2N2 H4 + 2NO2 --------- 3N2 + 4H2O

Kc = [N2]^3.[H2O]^4 / [N2H4]^2.[NO2]^2
