Before Answer a) Answer b) Answer c) Answer d) Factors that affect rates of substitution reactions: Some of the factors that affect rates of ligand substitution reactions are those that also affect thermodynamic stability. A stable atom is an atom that has enough binding energy to hold the nucleus together permanently. The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. When is a reaction thermodynamically favorable? Thermodynamic stability depends on whether or not the reaction is spontaneous. Thermodynamic stability depends on Bethesda, MD 20894, Web Policies In the human genome, there is an over-representation of single-nucleotide-loop G4 motifs (G4-L1), which are highly conserved among humans and show a striking excess of the thermodynamically least stable G4-L1A (G3AG3AG3AG3) sequences.

Also if there are multiple transition states the one closest to the energy level of the product is the most stable transition state. Why sulphonation of naphthalene gives different products at different temperature. For example, nitration of toluene is kinetically controlled. There's more positive charge if we consider the other blobs of protein in milk. Another example is the gasoline in the tank of your car. Basically, thermodynamics focuses on whether or not the reaction can occur on its own without any outside force (spontaneous), while kinetics focuses on how fast a reaction occurs (rate).
