Question

The rate constants of a certain reaction at different temperatures were recorded as shown below.

Calculate the activation energy, ΔG^‡, ΔH^‡, ΔS^‡ of the reaction at 50°C. Express your answers to three significant figures.

Accepted Answer

E_{a} = 21.3 kcal/molΔ$$G^{‡} = 26.7 $$kcal/molΔ$$H^{‡} = 20.7 $$kcal/molΔ$$S^{‡}$$ = –0.0186 kcal/mol∙K

Answer

E_{a} = 33.8 kcal/molΔ$$G^{‡} = 44.6 $$kcal/molΔ$$H^{‡} = 33.2 $$kcal/molΔ$$S^{‡}$$ = –0.0310 kcal/mol∙K

Answer

E_{a} = 31.4 kcal/molΔ$$G^{‡} = 27.8 $$kcal/molΔ$$H^{‡} = 24.2 $$kcal/molΔ$$S^{‡}$$ = –0.0310 kcal/mol∙K

Answer

E_{a} = 41.2 kcal/molΔ$$G^{‡} = 32.4 $$kcal/molΔ$$H^{‡} = 28.1 $$kcal/molΔ$$S^{‡}$$ = –0.0174 kcal/mol∙K
