asked 06/07/18What is the concentration of each gas once equilibrium is reached?
Can someone please let me know if I did this right?
1.800 mole of N2O4(g) is injected into a closed 1.00L container.
Kc=4.66 x 10-3 at 298K
N2O4 (g) ⇌ 2NO2 (g)
what is the concentration of each gas once equilibrium is reached?
I set up an ICE table as follows:
I 1.80 0
C -x +2x
E 1.80-x 2x
then input the values from row E into Kc equation:
4.66 x 10-3= (2x)2
(1.80-x)
using the quadratic equation I found x= 0.0452, and x= -0.0463
using the positive value for x to find the concentrations of each gas at equilibrium, I found:
[N2O4]= 1.80-x
1.80-0.0452
1.75M
[NO2]= 2x
2(0.0452)
0.0904M
