  2. The reaction is non-spontaneous
  3. The reaction is at equilibrium
  4. The reaction is exothermic

Questions & Step-by-Step Solutions

If a reaction has a ΔG of +5 kJ/mol, what can be inferred?
  • Step 1: Understand what ΔG means. ΔG stands for Gibbs free energy change, which tells us about the energy of a reaction.
  • Step 2: Know the significance of the sign of ΔG. A positive ΔG value means that the reaction requires energy to occur.
  • Step 3: Recognize that a reaction with a positive ΔG is non-spontaneous. This means it will not happen on its own without added energy.
  • Step 4: In this case, since ΔG is +5 kJ/mol, it confirms that the reaction is non-spontaneous.
  • Gibbs Free Energy (ΔG) – ΔG indicates the spontaneity of a reaction; a positive value means the reaction is non-spontaneous under standard conditions.
