To predict whether the reaction is spontaneous or non-spontaneous it is based on the value of:
Correct answer: D. ∆G
- A. ∆H
- B. ∆E
- C. ∆T
- D. ∆G
Explanation
Based on the information provided, the correct option for predicting whether the reaction is spontaneous or non-spontaneous is ∆G. ∆G represents the change in Gibbs free energy during a chemical reaction. It is a measure of the spontanity of a reaction. A negative ∆G indicates a spontaneous reaction, meaning the reaction can occur without the need for external energy input. A positive ∆G indicates a non-spontaneous reaction, meaning the reaction requires an input of energy to occur.

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.

A macroscopic property of a system which has some definite values for initial and final states, and which is independent of the path adopted to bring about a change is called:
According to Born Haber's cycle, ∆Hlatt of ionic compound is determined by the formula:
If a chemical change takes place by several different routes, the overall energy change is the same, regardless of the route by which the chemical change occurs provided the initial and final conditions are the same. This is in accordance to:
Enthalpy is a state function. Standard enthalpy change is measured at:
Internal energy is a sum of kinetic energy and potential energy. If internal energy of a system increases, then all of the following changes may take place EXCEPT:
