Question

Pick out the wrong statement (A) The standard free energy of formation of elements is zero (B) A process that leads to increase in free energy will be spontaneous (C) A process accompanied by decrease in entropy will be non-spontaneous under normal conditions. (D) Enthalpy of combustion is always negative

Tardigrade Admin · Accepted Answer

Δ G gives a criteria for spontaneity at constant pressure and temperature. (I) If Δ G is negative (< 0), the process is spontaneous. (II) If Δ G is positive (> 0), the process is non-spontaneous.

Q. Pick out the wrong statement

The standard free energy of formation of elements is zero

A process that leads to increase in free energy will be spontaneous

A process accompanied by decrease in entropy will be non-spontaneous under normal conditions.

Enthalpy of combustion is always negative

$Δ G$ gives a criteria for spontaneity at constant pressure and temperature.
(I) If $Δ G$ is negative $(< 0)$ , the process is spontaneous.
(II) If $Δ G$ is positive $(> 0)$ , the process is non-spontaneous.
