Problem- Write an equilibrium expression for each chemical equation (Careful, some contain liquids and solids).
1) SbCl5(g)? SbCl3(g) + Cl2(g)
2) 2BrNO(g)? 2NO (g) + Br2(g)
3) CO32-(aq) + H2O(l)? HCO3-(aq) + OH-(aq)
4) 2KClO3(s)? 2KCl(s) + 3O2(g)
I want you to clarify the chemistry in this above problem.
