question 58

Multiple Choice

The equilibrium constant for a reaction is determined at several temperatures by measuring concentrations of reactants and products.

• B) ln(K); 1/T; \(\Delta\)H°; \(\Delta\)S°
• C) ln(K); 1/T; \(\Delta\)H°/R; \(\Delta\)S°/R
• D) ln(K); 1/T; \(\Delta\)S°/R; \(\Delta\)H°/R
• E) ln(K); 1/T; -\(\Delta\)H°/R; \(\Delta\)S°/R
