Factors

Postby Courtney McHargue 1I » Tue Feb 19, 2019 8:02 pm

What factors influence the value of delta G in a reaction? Is it mainly influenced by what's present in the reaction or what is produced/given off?

Since delta G is calculated for by the equation delta G = delta H - T(delta S), the factors that affect delta G are the enthalpy of reaction, the temperature that the reaction takes place at, and the entropy. A negative enthalpy, high temperature, and high entropy makes for a spontaneous reaction (negative delta G), while the opposites make for a nonspontaneous reaction (positive delta G).

Like said above, if you look at the individual factors that determine what delta G is in the equations, inferences can be made such as higher temperatures leading to a greater chance of a reaction being spontaneous or a negative enthalpy change.
