Question

The KCl ?H°soln = 17.3 kJ/mol, and ?S°soln = 0.0763 kJ/mol.K. Is this reaction endothermic or exothermic? Which term contributes most to the ?G°soln of KCl, ?H°soln or T?S°soln? The KCl ?H°soln = 17.3 kJ/mol, and ?S°soln = 0.0763 kJ/mol.K. Is this reaction endothermic or exothermic? Which term contributes most to the ?G°soln of KCl, ?H°soln or T?S°soln?

Explanation / Answer

Given

dHo(soln) = +17.3 kJ/mol

The reaction is endothermic in nature

dHo(soln) contributes the most to the dHo(soln) for KCl
