The condition for a reaction to occur spontaneously is

The relation $\Delta G = \Delta H - T\Delta S$ was given by

Let us consider an endothermic reaction which is non-spontaneous at the freezing point of water. However,the reaction is spontaneous at the boiling point of water. Choose the correct option.

For the vaporization of water at $1 \ atm$ pressure,the values of $\Delta H$ and $\Delta S$ are $40.63 \ kJ/mol$ and $108.8 \ J/K \cdot mol$ respectively. At what temperature $(K)$ will the change in Gibbs energy $(\Delta G)$ be zero (in $.4$)?

Which of the following conditions results in a spontaneous chemical reaction?

$A$ process will be spontaneous at all temperatures if
