• From the relationship between Gibbs free energy, enthalpy, entropy and temperature we know: \$\Delta G = \Delta H - T\,\Delta S\$, and that a reaction is only thermodynamically favored when \$\Delta G < 0\$. And even when \$\Delta G < 0\$ the reaction may still not occur at a measurable rate because it has too high an activation energy.
• So, we want to say 25 + 273 = 298 Kelvin. So that's the temperature we'll use in our calculations. Now we want to look at our first problem here, we're given a delta H value of 15 kilojoules per mol and delta S of 29.5 joules per mol Kelvin. We're going to use the equation delta G = delta H- T delta S to solve for our Gibbs free energy.
