mol gas N2O4 | = | 0,5 a mol |
mol gas NO2 | = | a mol |
mol gas total | = | 1,5 a mol |
PNO2O4 | = | (mol NO2O4/mol total) x Ptotal |
= | (0,5a/1,5a) x 1 atm | |
= | (1/3) atm |
PNO2 | = | (mol NO2/mol total) x Ptotal |
= | (a/1,5a) x 1 atm | |
= | (2/3) atm |
Kp | = | (PNO2)2 (PN2O4) |
= | (2/3)2 (1/3) | |
= | 4/3 |
