1. The problem statement, all variables and given/known data CO(g) + NH_3(g) ...> HCONH_2(g) euilibrium constant is: K = 0.207 at 400 K If a reaction is filled with intial concentrations 2.20 M of CO and 2.60 M of NH_3 and the reactanats are allowed to raect at 400K/ what will be the concentrations of CO at equilibrium ? 2. Relevant equations Keq = [HCONH_2] / [CO] [NH_3] 3. The attempt at a solution 0.207 = (X) /(2.20-X)(2.6-X) But I'm getting the wrong answer for x. Please help me.
