Which is true for a spontaneous endothermic process?
Correct answer: B. delta G<0
- A. delta H<0
- B. delta G<0
- C. delta S<0
- D. delta G>0
Explanation
Explanation: A spontaneous endothermic process has a negative change in Gibbs free energy (delta G<0), indicating that it can proceed spontaneously, even while absorbing heat.

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
