1.	WHat is the expression of KC of the chemical equation Ag2O(s) + 2HNO3(aq) \(\rightleftharpoons\) 2AgNO3(aq) +H2O(l)?(a) [AgNO3(aq)]^2/[HNO3(aq)]^2(b) [AgNO3(aq)]/[HNO3(aq)]^2(c) [AgNO3(aq)]^2/[HNO3(aq)](d) [AgNO(aq)]^2/[HNO3(aq)]^2The question was posed to me in semester exam.The question is from Homogeneous Equilibria in section Equilibrium of Chemistry – Class 11
Answer» Right choice is (a) [AgNO3(aq)]^2/[HNO3(aq)]^2 To explain: It is important that for the EXISTENCE of HETEROGENEOUS equilibrium pure solid or liquid must also be at equilibrium, but their concentrations do not APPEAR in the expression of the equilibrium CONSTANT. So here KC = [AgNO3(aq)]^2/[HNO3(aq)]^2.
