WebFor example, when Mr. Khan was talking about a spontaneous Gibbs free energy process - if delta H (enthalpy) was positive and delta S (entropy) was positive, the temperature would need to have a "High T" or high enough to make delta G (Gibbs free energy) negative overall and thus a spontaneous process. WebThe temperature plays an important role in determining the Gibbs free energy and spontaneity of a reaction. Δ G = Δ H – T Δ S. If we examine the Gibbs free energy change equation, we can cluster the components to create two general terms, an enthalpy term, Δ H, and an entropy term, – T Δ S. Depending on the sign and magnitude of each ...

If Δ G is negative, then it is energetically favourable for the reaction to occur - in other words, there will be a release of energy due to the reaction. ireland lng predator

"WebA spontaneous process is one that occurs on its own, without any energy input from the outside. For example, a ball will roll down an incline; water will flow downhill; ice will melt into water; radioisotopes will decay, and the iron will rust. Name two factors which favour a spontaneous reaction. Enthalpy is the total heat content of the system. " - How does delta g relate to spontaneity
