NCERT · Class 11 · Chemistry · Chemical ThermodynamicsWhat is the condition for a chemical reaction to be at equilibrium in terms of Gibbs free energy change ($\Delta G$)?
Step-by-Step Solution
For a system at constant temperature and pressure, the condition for equilibrium is $\Delta G = 0$. If $\Delta G < 0$, process is spontaneous, and if $\Delta G > 0$, it is non-spontaneous.
