🤓 Based on our data, we think this question is relevant for Professor Petros' class at UNT.
When dealing with equilibrium and Kc:
• Kc → equilibrium units are in molarity
• Kc is an equilibrium expression:
▪ only aqueous and gaseous species are included in the equilibrium expression
▪ the coefficient of each compound in the reaction equation will be the exponent of the concentrations in the equilibrium expression
Step 1: Molarity of ICl
Molarity of ICl = 0.100 M
In an analysis of interhalogen reactivity, 0.500 mol of ICl was placed in a 5.00-L flask, where it decomposed at a high T:
2ICl(g) ⥫⥬ I2(g) + Cl2(g)
Calculate the equilibrium concentrations of I2, Cl2, and ICl (Kc = 0.110 at this temperature).
