Consider the equilibrium system: N2O4 (g) = 2 NO2 (g) for which the Kp = 0.1134 at 25 C and deltaH rx is 58.03 kJ/mol. Assume th
at 1 mole of N2O4 and 2 moles of NO2 are introduced into a 5 L contains. What will be the equilibrium value of [N204]? A) 0.358 M
B) 0.042 M
C) 0.0822 M
D) 0.928 M
E) 0.379 M
Equilibrium constant is the ratio of the concentration of products to the concentration of reactants each term raised to its stochiometric coefficients.
Using ideal gas equation :
P = pressure of gas
V = volume of gas
n = no of moles
R = gas constant
T = Temperature
pressure of =
pressure of =
at t= 0 5 atm 10 atm
at eqm (5-x) atm (10+2x) atm
pressure of at equilibrium = (5-(-4.48))= 9.48 atm
