Which of the following statement is correct?
- A \(\Delta G\) is equal to \(\Delta G^{\circ}\) when the system is at the standard state.
- B \(\Delta G^{\circ}\) is zero when the system is at equilibrium.
- C \(\Delta G\) measures activation energy of a reaction.
- D When \(\Delta G\) is positive, the reaction should proceed forward to form more product.
Answer & Solution
Correct Answer
(A) \(\Delta G\) is equal to \(\Delta G^{\circ}\) when the system is at the standard state.
Step-by-step Solution
Detailed explanation
(a) \(\Delta G=\Delta G^{\circ}\) for a standard system of STP condition \(\left(25^{\circ} \mathrm{C}, 1 \mathrm{~atm}\right)\). The corrected statements of options-(a), (c) and (d) will be like, b) At equilibrium state, \(\Delta G=0\). (c) \(\Delta G\) measures spontaneity of…
