Question

A reaction has a large positive value of delta G degree at 298 K. The value of the equilibrium constant for this reaction at this temperature would be . much less than 1 much greater than 1 approximately 1 No conclusion can be drawn Which reaction has a delta S degree rxn > 0? 2H2(g) + O2(g) rightarrow 2H2O(g) Ag+(aq) + Cl-(aq) rightarrow AgCl(s) 2NH3(g) rightarrow 3H2(g) + N2(g) 2H2(g) + O2(g) rightarrow 2H2O(I) What is the correct equilibrium expression for this reaction? CaCO3(s) + 2HCI(aq) CaCl2(aq) + H2O(I) + CO2(aq) Kc = [CaCl2]/[HCl]2 Kc = [CaCl2][CO2]/[HCl]2 Kc = [CaCl2][H2O][CO2]/[HCl]2 Kc = [CaCl2][H2O][CO2]/[CaCO3][HCl]2 What is the molar solubility of TIBr in pure water at 25 degree C?
