Question

In the following equation
ΔG = ΔG° + RT  nK

Quizplus · Accepted Answer

The equation given is the standard change in free energy equation, where ΔG° is the standard change in free energy, R is the gas constant, T is the temperature in Kelvin, and n is the number of moles of electrons transferred in the reaction. The addition of RT 11eaaf91_9e10_0474_892c_b16d1f81fd54_TB6422_11 nK in the equation refers to the non-standard conditions.

Option A, K = 1, is not relevant to the given equation, as there is no mention of any equilibrium constant in the equation.

Option B, ΔG° = 0, would mean that the reaction is at equilibrium under standard conditions, but under non-standard conditions (as indicated by the RT term), the reaction would no longer be at equilibrium. Therefore, ΔG would not be equal to ΔG°.

Option C, ΔG = ΔG°, would only be true if the reaction is at equilibrium under non-standard conditions. However, there is no information given in the equation or question stem to suggest this is the case.

Option D, ΔG = 0, is the best choice. This would mean that the reaction is at equilibrium under the given non-standard conditions.
