Chemistry - Thermodynamics - II Question with Solution | TestHub

To identify the direction of a spontaneous change we can look for the direction that gives an increase in entropy of universe or a decrease in Gibbs free energy of system. Explain how these two apparently different criteria actually amount to the same thing, noting the relationship between entropy, enthalpy and Gibbs energy.

Here are some standard values for 27°C

Use : R = $\frac{25}{3}$ J/mol-K, lnx = 2.3 log x
