Organic chemistry mcat khan academy10/7/2023 ![]() The reactants (A) are at higher free energy than the products (B). For example, if the forward reaction has a ΔG value of less than 0 it is spontaneous. When considering the thermodynamics of a reaction, we can look at the ΔG value for both the forward reaction and backward reaction. ![]() We can examine this using an example of a reactant A in a reversible reaction with product B. This choice of mechanism can influence your choice of reaction conditions such as concentration, temperature, pressure, and solvent.įor example, the free energy in a reversible reaction is important in both the forward and backward reaction. ![]() This leads to different products due to the selectivity or stereoselectivity of the reaction. kinetic factors).Ĭhoosing the mechanism of control for a chemical reaction is important as it not only determines the composition of the product in a reaction mixture, but also determines the reaction pathway that is taken. thermodynamic factors) and the rate of product formation (i.e. The potential outcome of a reaction is usually influenced by two factors: the relative stability of the products (i.e.
