2 cards from this section. Quick, good the night before a test.
What does a negative ΔG° indicate about a reaction?
Think about whether energy is needed for the reaction to occur.
What is the equation relating ΔG° and K?
Remember the variables involved in the equation.
What happens when ΔG° is negative?
Think about spontaneous processes.
If ΔG° is positive, what can be said about K?
Consider how spontaneity relates to reactant concentration.
For the reaction 2H₂(g) + O₂(g) ⇌ 2H₂O(g), it was found that at 298 K, ΔG° = -237.1 kJ. Calculate Kp for this reaction at this temperature.
Ensure unit conversion consistency and use properties of logarithms.
Discuss how an increase in temperature would alter the value of K for the reaction N₂(g) + 3H₂(g) ⇌ 2NH₃(g) (ΔH° = -92.4 kJ).
Think about how temperature affects heat in chemical reactions.
