Reactions, Equilibrium

Postby ASetlur_1G » Sun Dec 01, 2019 10:51 am

In class, Dr. Lavelle kept mentioning how reactions were favored to the right or left. What does that mean?

Remember that many chemical equations are at equilibrium, where there are forward and backward reactions happening all the tine.

If a reaction is "favored to the right," the reactants will react/decay to form more products. If the reaction is "favored to the left," then the products will react/decay to form more of the reactants.

Given most chemical reactions (consider the dissolving of salt in water) reactions are proceeding in both directions at all times. In our saltwater example, NaCl is both being dissolved and reforming at all times. In most chemical reactions, one direction of the reaction takes more energy, and so normally, you would observe this reaction taking place at a lower rate than its reverse reaction. Changing conditions like reactant concentrations and temperature can affect the direction favored by the reaction equilibrium. A right-favoring equilibrium favors the forward reaction, while a left-favoring equilibrium favors the reverse reaction. Hope this helped!

Is there notation to show the direction a reaction is favoring, or do you still just write the double pointing arrow?

So does it mainly depend on what is written on each side of the equation?
