Question

under what conditions of Gibbs energy of process is found a spontaneous

Answer 1

For a process to be spontaneous, the Gibbs free energy should be negative, i.e. Delta G <0.

Answer 2

Enthalpy change Entropy change Gibbs free energy Spontaneity positive positive depends on T, may be + or - yes, if the temperature is high enough negative positive always negative always spontaneous negative negative depends on T, may be + or - yes, if the temperature is low enough positive negative always positive never spontaneous
