Question

At 25 C, the decomposition of dinitrogen tetraoxide
N2O4(g) 2 NO2(g)
has an equilibrium constant (Kp) of 0.144. At equilibrium, the total pressure of the system is 0.0758 atm. What is the partial pressure of each gas?
A.0.0745 atm NO2(g) and 0.0385 N2O4(g)
B.0.0549 atm NO2(g) and 0.0209 N2O4(g)
C.0.0531 atm NO2(g) and 0.0227 N2O4(g)
D.0.0502 atm NO2(g) and 0.0256 N2O4(g)
E.0.0381 atm NO2(g) and 0.0377 N2O4(g)
