Homework Answers
1) solubility is the maximum amount of substance which can be dissolved in specified amount of solution or solvent.
2) equilibrium constant is dependent on the nature of reactants
3) By increasing pressure chemical equilibrium shifts in the direction in which less number of gaseous moles are present and vice versa
4) Balanced chemical reaction,
2NO2 ----> 2NO + O2
Keq = (2.2)2×1.1/(0.80)2
=> 8.32
