A reaction is spontaneous at constant temperature and pressure when what condition is met?
Answer and explanation
Correct answer: D. The change in Gibbs free energy is negative
- Step 1: Delta G = delta H - T delta S. Step 2. A negative value means the process is spontaneous. Answer: delta G is negative. Why not the others: In elemental sodium metal, sodium has an oxidation state of 0, while in the sodium ion (Na+) it has an oxidation state of +1; +2 is not an accessible alkali metal state.
