### Homework 5I.25

Posted:

**Tue Jan 14, 2020 10:18 am**I've set up an ice table so that the equilibrium concentrations are as follows:

[SO2] = 0.02M - x

[NO2] = 0.04M - x

[NO] = 0.02 + x

[SO3] = 0.03 + x

And I've set up the equilibrium concentration as Kc = [NO][SO3]/[SO2][NO2], and letting these equal 85. My expanded equation for Kc is (x^2 + 0.05x

+ 0.0006)/(x^2-0.06+0.0008). I feel like I am setting it up right but I keep getting a different answer than what the answer key shows. Can someone explain to me how to do this problem correctly or help me identify any mistakes that I made? Thanks
